I need a little help to install my Oil PSI and Temp gauges. I got them for free awhile back and I need a sender for both I believe. I'm not quite sure though. They are just the gauges and that is it. If I need to buy a new sender lemme know so I can look into it. Is there a way to splice the wires from the sender to the gauge? I have never done this install before so alot of help is needed. Thanks.
