remote trunk

[hyunelan2]

I remember briefly seeing this on the Old EXD, but I don't think it went very far. What would be involved in making a remote trunk release i.e. opening the trunk with a remote? Anyone know a list of materials and an approximate cost? I'm sure this is going to require an aftermarket alarm system, but what other parts will be needed, since we don't have a remote trunk already?

[doothedeww]

Any aftermarket alarm should do, as long as it has extra channels. For mine i took the emergency handle out of my trunk lid and mounted a solonoid to the metal crossmember. You will need a relay for this to work too since the output of the extra channels on a alarm is like 200ma. You will need to run two wires to the trunk, i used 16awg speaker wire since it is two conductor and it was laying around. I got a viper solonoid 522T. You can get it for $25 plus shipping from etronics.com

[hyunelan2]

Excellent. Exactly the information I was looking for. If only all questions were answered this easily...

[southpawboston]

if you want you can even do this with the stock keyless system without upgrading to an aftermarket alarm. you just need to buy a pulse-timer relay (PAC model TR7) and interface it with the stock ETACS. you can program it to activate the trunk release solenoid relay described by doothedew by pressing the unlock button twice within a couple of seconds. you can add tons of accessories to the stock keyless system.

No F'n Way! That would be completely AWESOME. I don't need an alarm, i just thought i would need one in order to put these extra things on. Where can I find a pulse-timer relay (PAC model TR7).

So let me get all this straight. I get the solenoid and hook it up with a relay (power from battery, grounded, 'activation wire' to new etacs module.) Then I put in this PAC on the ETACS, and I will be able to open the trunk by pressing unlock twice? This is too cool. You're the man southpaw.

EDIT
Found it, this thing is awesome!

[southpawboston]

yep. the TR7 timer needs to be "programmed" to do what you want (number of pulses to activate, etc), but it's all in the instructions that come with it. if you end up going forward with all this just PM me and i'll help you set it up and hook it up to the right ETACS wires.

[Luckydvl]

now i am intrested for this also so southpaw we going to need your expertise.
so we need module, and trunk solenoid, and a diagram from u on how to install it

[DragoZERO]

thats not a bad idea. i am getting the viper 2way eventually and that has an aux option and all. i have to see how much my friend could do it for, he works at a garage and can get prices and install it for me.

[hyunelan2]

Well Southpaw, we've got a project. I won't be buying the parts for about a week though (whole new bedroom furniture set, spoiler, and a bunch of new tools are on my credit card, need to wait for that bill to clear before I spend more). Prob. order this stuff the end of next week, that'll be a great project - can't wait.

[Rdubois]

I've asked people who put alarms in before about this and they said since it didn't come with that option it couldn't be done. Were they just blowing smoke up my ***? We are talking about popping the truck open with the stock remote right? What is overall cost to do this and how hard is it?

[hyunelan2]

Yes, that's what we're talking about, popping the trunk with the remote by holding down the button longer, or pressing it twice, three times, etc. I haven't done this yet, but am going to try it. So far the cost looks like it will be about $50, plus shipping, so maybe at tops $75 - (a little extra for wires, connectors, relays, etc). We will need to

1. Install a solenoid in the trunk to pull the trunk release cable.
2. Install a Pulse-Timer Relay on the ETACS system (must have factory keyless).
3. Connect the two and program the Pulse-Timer Relay.

That's what I know, Southpaw is the expert, I'm just a guinuie-pig (sp).

[Onelove5683]

WOW that thing is on sale for $22.00 !!!!

[hyunelan2]

And now I own it! $32.94/shipped. 1/2 of the pieces of the puzzle are now in the mail.

[southpawboston]

okay, just let me know when you get everything and i'll guide you through the ETACS and relay module hookup. you can find standard automotive relays for $5 at parts stores or radio shack, or wherever you buy the solenoid. i'll work on a diagram showing exactly how everything will go together.

rdubois-- i used to think that expanding the stock keyless system was hopeless until i learned about the pulse timer relay (thanks to santa fe forum moderator twospirits). this little module is incredible. it can be programmed to recognize a number of pulses and then create an independent pulse. the module will be hooked up to the alarm lights flash output and set to recognize four pulses. this way when you hit the unlock button twice you will get four light flashes and then the module will send a pulse to the trunk release solenoid. similarly, if you were to hit the lock button four times quickly you would generate the same effect.

[XTRAWLD]

It can be done! I remember this convo on the old XD too. I think the only thing you might encounter is it popping up with enough force as to not close back on itself. (Mainly for the hatch.) Remember when Jay was selling spoilers for the cars, he was selling a package of the spoiler and additional hatch trunk cylinders (prolly not the right term but I think you guys know what I'm getting at) because the spoiler would be added weight on the trunk and it wouldn't pop open properly?

[hyunelan2]

Excellen point Xtra, I have an idea already, if this will be a problem. I was thinking of puttin on a Gas-strut, so I just pop the trunk and it would open fully. I had those on my Camaro (natually, they all did), but I liked being able to push the button and have the trunk (hatch) raise all the way up to it's fulles level. That way if your hands are full, you don't even need to mess with the thing. I haven't examined the truk, but it this is needed I will probably affix it to the arm that attaches to the trunk. (sorry that location doesn't exist for you hatch owners).

[southpawboston]

that's correct xtrawild. but if a person who wants to do this mod doesn't already have a problem popping their trunk lid using the driver's side remote release, then there will be no problem using the solenoid.

[hyunelan2]

Hey southpaw, once this solenoid is in place, will I still be able to use the driver's side release, or will I only be able to operate the cable with the solenoid?

P.S. Off to order the solenoid, I have no patients for waiting for things - so mu CC bill will just be a little bigger.

EDIT - everything's ordered. Now I just have to wait for stuff to come in - that's always the hardest part. The Solenoid was 32.98/shipped for a total cost of 65.92/shipped. I have some relays/wires/connectors/solder already, so this will be the total cost of this project.

[jjos1]

wow thanks great! two questions can you add a window mod auto up or down and is there much of a difference between 04 alarms and 03 alarms other than the key pad ?

[hyunelan2]

I think the window up/down is just a limit-switched relay that could prob. be hooked up to this type of system. Southpaw would be able to answer you for sure, but I think there's hope.

[Luckydvl]

ok now i got to order mine next hey hyunlan when u get the stuff dont forget to take some good pics cause i am really interested in doing this mod also always like to pop the trunk before i drop the grocerys. LOL

[southpawboston]

as far as the logistics go for mechanically hooking up the solenoid, that's something that doothedew has done, not i. so he'd be able to comment more on that. my guess is that it won't interfere at all with the action of the stock remote release.

jjos-- you can add 4 window roll up or roll down (or both) to work with the factory remote. but you can't have that AND the trunk release. it's a pretty big project to do the window roll up/down. for each direction (up or down) you'd have to buy one pulse timer relay and one 4-window roll up/down module. so you're looking at a total of $60 for roll up and $60 for roll down (you also don't have to do both). that's getting cheap modules on ebay. then you'd have to run extra wires into the driver's door and do a lot of electrical hookups. but it's definitely do-able.

[XTRAWLD]

Getting the trunk to raise all the way up would be ideal....once that's done take a small video so we can all oooh and ahhh.

[doothedeww]

i removed the glowing emergency handle in the lid and put the solonoid there, that way the factory trunk release in the car is still functional. i would take pictures but i filled the whole lid with spray foam and dynamat extreme so it is not visible.

I know what you're talking about, after looking at my trunk. There's 2 seperate releases with 2 seperate cables on 2 seperate devices. 1 is the glowing handle, which pulls open the latch attached to the trunk lid. The other is off of the handle inside the cabin, and releases the latch in the bumper area of the car. So, you can put the solenoid in the handle's position on the trunk, and it will not have anything to do with the other release in the car.

(P.S. I think I just said the same thing, but in more words).

[CarbonGT]

I loved beaing able to close the windows and sunroof in my vr6 Jetta. That is an awesome feature. Cant wait to see how this goes. :)

[hyunelan2]

OK Southpaw, I got the Pulse Timer Relay in today. The solenoid will be here tomorrow. I'm all set (I can hook up the PTR without the solenoid for now if it doesn't show up on time). I'm glad you're helping me out with the wiring, there's a lot of different possible combinations in the instructions. The trunk will raise up all the way now, so that's no longer a factor.

[peters73]

I need to do this. This is cool.

Thanks.

[hyunelan2]

Update for those who are interested.

I installed the solenoid last Friday. I did not have to remove the emergency handle, just added the solenoid above it, 'between' the inner and outer sheet metals in the trunk. (you'll see what I mean). I'm wiring up the relay and finishing the project this Friday, I took the day off work so I will be able to get this all done for the weekend.

[Rdubois]

Cool. Make sure that you post some detailed pics of everything. I think this is a project I will want to try doing.

[hyunelan2]

It's done! It works! It's cool as hell! I'll have a detailed DIY (in conjunction with southpaw) as soon as I get a chance. I've had a hella-busy life the past couple of weeks. I have a few DIYs to write, but it really isn't that hard. I would suggest this mod in a heartbeat. Cost of parts: ~$65. Time involved: 1-3 hrs (depending on amount of breaks and procrastination - it took me 2.5, but I could've done it in 1). Cool *** remote trunk release with stock remote: priceless!

[DragoZERO]

nice. i'm def. doing this when i get my viper, it has an aux output. i'd suggest it to you guys, but its retail at best buy is $500. since i work there i am getting it for $140, hehe.

[04Elantra]

Wow...is the Best Buy discount that much for all employees? :eek:

If so, I would work there for a couple of months for the discount! :cool:

[DragoZERO]

this is what is called an 'accomodation' (sp?) but yeah. its part of the discount, and its the reason why i work there. those new kenwood fronts that are stock or w/e, that everyone likes, i got them for $35. haha.

[FalconKR5]

Southpaw,

What exactly would be involved in having all four windows and the sunroof open using one of these pulse-relays?

[da1tank]

this remote trunk sounds tight as mess, i'm gonna have to save up and do it soon

[southpawboston]

Southpaw,

What exactly would be involved in having all four windows and the sunroof open using one of these pulse-relays?

well you would need the pulse relay plus three window modules (they typically work two windows per module). you're looking at about $80 in parts.

then the installation would be rather advanced, much more so than for the remote trunk DIY. you'd really have to rip out the whole lower left side of the dash, remove the fuse box, and remove the driver's door panel. big job to say the least.

[nycbred]

which type of solenoid do you need ? and where could i find it

[Yellow_Elantra]

You can buy a window up/down controll module that is
already set up and all it needs is a "lock" pulse from the
factory alarm, from the ETACS.

I think DEI makes them

[southpawboston]

yellow, that's correct, but do you really want your windows to roll up EVERY time you lock your doors? on really hot days many people like to lock their doors with the windows kept open a crack. so, to be able to roll your windows up separately from locking the doors, it requires a pulse timer.

[nycbred]

This may seem crazy but I wanted to know, is i possible on an aftermarket system, to have the window module hooked up to the lock and unlock, and the trunk use the aux.
