I am wanting to wire the light on my temp gauge to the headlight switch, so that the gauge light comes on with all the other gauges. What wire should I splice into to do this? HELP ASAP please!!!

 

Uhhh..an ignition wire. Im not sure how many amps they pull but you may also want to consider adding a relay if its alot. If you have a volt meter test the wires under the steering column until you find one that has +/-12v when the ignition is on and almost none when the switch is off.

 

No i'm just talking about the wire for the light, not the wire for the gauge itself. Sorry, i should have mentioned that it is an electric gauge, not mechanical. I am talking about wiring the light into the back of the headlight switch

 

Im not sure what wire it is, but you can easily pull the pannel out where the switch is. Be careful cause in my car, my lights come on automatically, im not so sure the wire going to the swich goes hot once they come on.

 

Its a pretty easy job. Get behind your headlight switch and get to the wires at the petentiometer (the **** that dims or brightens your dash lights). With a test light find the hot wire that dims and brightens as you move the **** (petentiometer). Your test light will get bright and dim as you move the ****. That would be the wire that you want to splice into, and it will power your light at the gauge when the lights automatically go on or off as well as make the gauge dim or bright with the **** as well.

 

I did this like 6days ago to my car for my gauges I think it was the green wire?
