Okay, I've been searching the past hour, but I still haven't found what I need.

(Though I think I want a Tib multigauge now..)

I just received my three Prosport gauges yesterday, and will be installing them when I get the triple pod from Craig.

Here are the three gauges I bought:

http://prosportgauges.com/blue-air-fuel-ratio-gauge.aspx

http://prosportgauges.com/blue-wter-temperature-gauge.aspx

http://prosportgauges.com/blue-oil-pressure-gauge-52mm.aspx

So, the question is, how hard are these to install? I know a handful of you have put in aftermarket gauges, so I'm hoping someone can help. Each gauge came with everything I need (senders, harnesses, etc) so I just need to know WHERE I put them.

Any help would be GREATLY appreciated.

Thanks in advance.

Medium to Hard.

AF: Very easy. 3 wires. Power, ground, signal. Pin number 43 if I remember on the ECU (dont quote me on this).

Oil: Electrical, so easy. Probably 3-5 wires. 1-2 power, 1-2 ground, one signal. Signal goes to sender which is connected to an oil source. For this the best is to use the prosport oil sandwich plate. That's what I have in my car.

Water: The hardest of the three. You're going to need to drill and tap your water housing next to the stock sensor, where the thermostat is. Pretty easy but tapping aluminum reuires a bit more attention to detail than steel. Same as oil. Probably 3-5 wires aswell.

Oh, and add an extra wire each for that ''amber light'' switching thing those prosport gauges have.

Why would gauges have 5 wires? 2 for power you say? Well, it's because they are full sweep. My autometer gauges worked that way anyways. They could be different.

Munky

All power wires go to a source that comes on with ignition, correct?

Bingo. Cigarette lighter works but I recommend the dimmer for the ones that deal with the backlighting, sometimes night driving is a pain if you cant adjust the brightness.

Also another downer: In the drive-in theatre, the ****ing gauges stay open all the time if wired to the lighter. LOL. I used to tape stuff to them not to be bothered by the light :P I guess a switch can work too.

Munky

12-16-2007, 02:32 PM

I have a feeling this is going to be more of a pain than I thought...I'm not as automotive savvy as some people on here.

Where did you put your oil pressure sender?

KeWLKaT

12-16-2007, 02:35 PM

Like I said. I used the sandwich plate. Look for it in the prosport site, it's a spacer that goes between the oil pump and the oil filter. Easy maintenance, and best source to get the readins as opposed to the bolt on the side of the head where the pressure is only like 25 psi tops.

These things: http://prosportgauges.com/oil-filter-adaptor-plate.aspx

You need the M20 size.

You can kind of see it here on my car

So it goes between the oil filter and the oil pan?

Weird.

Don't oil filters have all those holes around the center hole? You would think something could leak out.

Keyan

i did a double take at those pics i thought that was my engine bay, it looks identical

So it goes between the oil filter and the oil pan?

Weird.

Don't oil filters have all those holes around the center hole? You would think something could leak out.

its like a filter extension, those holes around the center hole of the filter is so the oil can flow lol....of course the sandwich has a matching path for the oil to go...

Okay, here's the specifics:

The water temp gauge came with the following:

http://i18.photobucket.com/albums/b114/MunkyMofo/PC160578.jpg

The instructions say the following:

RED - Ignition 12V (+)
BLACK - Battery (-)
GREEN - Temp sensor
ORANGE - Dimmer/+ 12V to dim; Connect to headlight to activate

I'm starting to think that buying this (http://prosportgauges.com/water-temp-sender-radiator-hose-adaptor.aspx) would make it a lot easier than drilling/tapping.

Oil pressure came with the following:

http://i18.photobucket.com/albums/b114/MunkyMofo/PC160579.jpg

RED - Ignition 12V (+)
BLACK - Battery (-)
GREEN - Oil pressure Sender
ORANGE - ORANGE - Dimmer/+ 12V to dim; Connect to headlight to activate

I already bought this (http://prosportgauges.com/oil-filter-adaptor-plate.aspx), like you suggested Felix.

A/F came with the following:

http://i18.photobucket.com/albums/b114/MunkyMofo/PC160580.jpg

RED - Ignition 12V (+)
BLACK - Battery (-)
GREEN - O2 Sensor Signal
ORANGE - ORANGE - Dimmer/+ 12V to dim; Connect to headlight to activate

This one seems like it would be the easiest, once I get the correct ECU pin to tap into.

Cypher

12-16-2007, 07:40 PM

you can also just tap the correct wire from the o2 sensor if you don't feel like searching for the right pin.

KeWLKaT

12-16-2007, 08:33 PM

OK I confirm it is PIN 43 (damn I have a good memory)

quote: OK, I got my afr gauge installed (connected with o2 sensor from ECU #43)

Link: http://www.elantraxd.com/forums/showthread.php?t=6021&highlight=gauge

That adaptor would be pretty cool and make it easier for the rad hose.

And the oil sandwich plate is the shizznit. Trust me. If oil leaked I wouldnt have had it on my car, LOL.

Munky

12-16-2007, 08:36 PM

Awesome. Felix, you kick ***.

These won't go in for a while, I hate working on my car in the cold. I need to find a friend with a heated garage, lol.

Few more questions..

What does it mean by hooking to the headlight/dimmer? If I splice off the dimmer switch, will they come on even when the headlights are off?

Which hose would that adapter go on, the top or bottom?

KeWLKaT

12-16-2007, 08:39 PM

Munky

12-16-2007, 08:44 PM

The best would be the one on top in my opinion.

BUT:

The reason why it would be good before the thermostat (drill and tap) is if the thing stays stuck or is starting to mess up you can easily know since the temp there is going up.... But if your T-stat stays stuck, the gauge wont show hot, you know what i mean? ;)

Hmm..that's a real good point.

I know I'm probably getting annoying by this point, but where exactly are you talking about drilling and tapping? Any way you could show me on the millions of engine bay pictures on this site?

KeWLKaT

12-16-2007, 08:46 PM

Let me see...

Cant find a proper pic.... But if you look at the thermostat housing, right after it there is the stock sensor. Somewhere near the stock sensor would be a good spot.

12-16-2007, 08:53 PM

Was thinking of getting a few aftermarket gauges instead gonna get the scan gauge thingy

Keyan

12-16-2007, 09:00 PM

prosport wiring is weird.

you need a 12v constant for the memory, and a switched power for them to turn on (it says to use ACCY but use ON, if you want to just listen to music the gauge will just beep at you becuase the engine isnt on and it thinks the vitals are dead...) and being that they are 2 color gauges, you have to hook them up to certain things to get the different color combinations. its weird.

Munky

12-17-2007, 09:28 AM

So, due to the weird wiring I should put them on a switch?

Keyan

12-17-2007, 09:34 AM

no, just wire them up and verify its set up the way you want before re-assembling everything so you dont have to take it back apart again, lol.

Munky

12-17-2007, 12:38 PM

James, you're one smart cookie.

Once I get the pillar, and a day in a heated garage, I'll start on this and write up a detailed DIY.

Sweet the DIY will help me to know where you wired your + .... I need to wire up 4-5 guages myself soon.

KeWLKaT

12-17-2007, 01:11 PM

4-5 gauges? WTF? lol? There is no need for 4-5 gauges IMO :P

Cypher

12-17-2007, 01:33 PM

all you really need is: boost, EGT and wideband for a turbo setup IMO. all of which are simple as hell to install

KeWLKaT

12-17-2007, 01:47 PM

all you really need is: boost, EGT and wideband for a turbo setup IMO. all of which are simple as hell to install

Actually the point of the wideband surpasses greatly the point of an EGT. If you have a WB and an EGT, it is kind of very useless.

I would say that critical things to have are: Boost, Oil Pres (trust me, had a lot of problems with that, when you modify the oil system of a stock car you need this), and some type of AF monitoring (Either wideband (best) or at least EGT). And if you have an auto I guess auto trans oil temp.

j0hnh0lmes

12-17-2007, 03:23 PM

Oil Temp
Oil Pres
Boost
A/F
EGT
..... and I think there is one more

I'm only doing A/F & EGT b/c I'll get the wideband later on....

Yay for that sandwich plate. I have an electric oil pressure gauge that's been unhooked for, oh, probably +2 years now, lol. I had it hooked up with some fittings to "T" it in with the OEM oil pressure switch for the dummy light. That lasted for a while but started to leak, so I just removed it and have had a ricer gauge since then. Maybe after Christmas I will look into ordering one of those.

KeWLKaT

12-17-2007, 10:45 PM

Its a shame, I just sold my old one, lol ;)

so are there issues with the M20?

no that is sometinh different

KeWLKaT

12-18-2007, 01:46 AM

He is talking about replacing the stock sensor totally. However that is not an option as you will have the turbo in the way.

hyunelan2

12-18-2007, 11:22 AM

I think the reason that most people's fittings leak is they are using the wrong adapter. The hole in the block for the OE sensor is 1/8 BSPT not NPT. I am usig the BSPT fitting, and have had no issues at all.

Yes, I'm pretty-sure that was my problem.

So, to hook up the Autometer Sending Unit, and the OE sending unit in the same position, I will need a 1/8 BSPT nipple, to a 1/8 BSPT "T", hook the OE unit to the "T", then use a 1/8 BSPT to 1/8 NPT adapter on the other side of the "T" and put the Autometer SU to that. Is that what you did?

Or did you simply eliminate the OE pressure switch? I don't want to do that, because frankly, when my wife drives the car I'd like for it to have a dummy light if there was a problem, rather than having to have her monitor the gauge.

Keyan

12-18-2007, 12:07 PM

I have seen more-than-one the T getting too much stress on it and snapping off, spilling oil everywhere destroying the motor.

If you go that route, support it or dont go that route. lol

Sounds a bit risky..:eek:

hyunelan2

12-18-2007, 12:16 PM

I think it's easier to find the sandwich plate than the handful of adapters to make everything fit with a T anyway.

Munky

12-18-2007, 12:17 PM

Why not get the Prosport sandwich plate, Mike? It's ~$40 and felix says its MUCH easier and well worth it.

http://prosportgauges.com/oil-filter-adaptor-plate.aspx

hyunelan2

12-18-2007, 12:26 PM

Yeah, that's what I will probably do. My only hangup with that, is that the dealer does all my oil changes (promotion when I bought the car $6.95 for everything, for the life of my car) and I could see the oil change tech going WTF when something is not stock.

Munky

12-18-2007, 12:26 PM

Ask them next time you get your oil changed. Tell them exactly what it does and where it goes beforehand, and it might alleviate future problems.

Slapshotman7

12-21-2007, 11:30 PM

As I am lazy, I'm hoping someone here knows the correct size to get for the radiator hose adapter?

KeWLKaT

12-22-2007, 01:55 AM

Like I said... dont get the hose adapter....

If your t-stat is stuck open youll never know. Before the dummy gauge on the stock cluster goes in the red, that is.

alienman

12-22-2007, 03:47 AM

I have been using the T set up for my oil pressure gauge for a few years now and I haven't had any problems. Heres a pic of it attached. The oil seepage you see is stupidity on my part as I didn't have it tight when I first tried it out. I was rushing working in the damn cold weather...

Great thead guys. I had been looking at getting some guages but have been depressed about the cost and nervous about the install. This clears that all up.

Slapshotman7

12-24-2007, 12:44 PM

Just ordered my gauges. :D

Munky

12-24-2007, 01:36 PM

Which ones did you get?

Slapshotman7

12-24-2007, 01:59 PM

Hate to be a copy cat, but same as you.

Prosport Blue Oil Pressure, A/F ratio, and water temp. Also got the oil filter adapter plate so its easier to get the oil pressure gauge set up.

Already got an email stating its been shipped, they work fast, wasn't expecting that on xmas eve!

Munky

12-24-2007, 04:06 PM

Prosport has the fastest shipping, it's amazing. I got the sandwich plate two days after ordering it.

Slapshotman7

12-24-2007, 04:11 PM

Yea I was amazed, I wasn't expecting anything until later this week.

Munky

12-24-2007, 06:21 PM

As soon as I get my pillar I will spend a weekend installing the gauges, with a full DIY write up.

It would be easier to get a 1/8 bspt (m) to 1/8 NPT (F) adapter and a regular 1/8 NPT tee. That would be a lot cleaner and a lot safer in the long-run.

And, yes, I did eliminate the factory sender all together.

Munky

02-27-2008, 04:05 PM

Okay, if I get the chance I will tackle the gauges this weekend. Let me get a refresher:

Oil pressure - I take off my oil filter, put the sandwich plate on, then screw the filter onto that? What do I connect to the sandwich plate? The sender goes on one side, but what about the other? I can take pictures if needed.

Water Temp - Drill and tap into the thermostat housing right behind the stock sensor? (Where is the stock sensor? I did a quick search after Felix posted up, but I couldn't find it. Knowing my luck, it's right in front of my face.) Couldn't I disconnect the stock one and put it in its place?

A/F ratio - Tap into pin 43 on the ECU. Does anyone have a pinout handy? What's the best way to do this?

If I'm wrong on any of this, someone please correct me.

Again, I appreciate all the help you guys have given me so far.

Munky

03-07-2008, 11:53 AM

Also, I heard you can tap into one of the O2 sensor wires for an A/F reading. Would that be just as affective as pin 43 in the ECU?

Cypher

03-07-2008, 11:58 AM

Yes and much easier. the signal wire is the green wire on the o2 sensor. I still haveto pick up a 3rd gauge. What should I get?

Munky

03-07-2008, 12:00 PM

Does it matter which O2 sensor?

Cypher

03-07-2008, 12:02 PM

Use the primary o2 sensor.

Slapshotman7

03-07-2008, 12:44 PM

Use the primary o2 sensor.

thats the one coming out of the exhaust manifold correct?

Cypher

03-07-2008, 12:47 PM

Yes.12345

Slapshotman7

03-29-2008, 05:06 PM

Yes and much easier. the signal wire is the green wire on the o2 sensor. I still haveto pick up a 3rd gauge. What should I get?

Two problems:

There is no green wire coming from the sensor. I have this:

Black, Blue, White, Gray, Yellow.

Second, and I haven't done much looking into this, where are you going to route the wires through the firewall?

Cypher

03-29-2008, 05:26 PM

Thats because you have a wideband gauge, unlike Munky who has a narrowband. Route them through the firewall near the brake booster.

Slapshotman7

03-29-2008, 06:22 PM

Ok, how do I wire mine than?

CornbreadXD

03-29-2008, 07:43 PM

anyone have any experience with Defi gauges? I may pick up a set of these prosports as well.

Munky

07-31-2008, 10:08 AM

Okay, I already have the sandwich plate and oil pressure sender installed, and all the wires soldered and ready to hook up.. and I plan to finally finish this this weekend.

I still have one question: Will I be able to get a proper reading if I tap into the signal wire on the stock water temp sensor, or should I take out the stock one and put the Prosport one in it's place? I don't want to tap and drill a new hole, and I don't necessarily care about the stock one, but I would like to keep both if possible.

maral01

07-31-2008, 05:41 PM

You should check with Prosport to see what voltage range their sender returns to the gauge (0-1V, 0-5V, etc...) and then compare with the OEM one. If they are identical, you could probably just tap into the OEM one and have good readings. If not, you will need to either buy an adapter (they sell some on the Prosport site and they are quite inexpensive) or tap somewhere close to your thermostat housing. Also, keep in mind that if you were to replace the OEM for the Prosport and that it does not output the same voltage as the OEM to the ECU, you could screw up the engine (i.e. let's say that it 0 Farenheit outside and your ECU thinks it's 50 Farenheit because of your new sender, it could do some damage engine wise AND it would probably screw up your whole fuel trim because your ECU would think your engine is either colder or hotter than it actually is).
