So...I'm reinstalling my gauges because my EGT was never properly wired amongst other things. I checked my wiring and everything works on a direct 12v source, but I'm looking for a 12v source that turns on/off with the parking/headlights so that I don't have to run my gauge lights off a switch. Could anyone please help me out here? If you have a pic that'd be awesome, if you have a verbal description, that should be just fine too. Once again I have managed to render my car temporarily undrivable. ...

 

hit up the dimmer switch power before it gets to the dimmer switch, would that work?

 

Guess I could try it. Long story short I'm locked out of my car right now and looking for ideas. I already need to tap something else into the dimmer though...was wondering if anyone knew the location of the parking/headlights power source though.

 

that was my first idea but I have NO clue where the wires are for thos... maybe just follow some wires from the steering collumn and use a voltage tester.

you're locked out of your car and this is your main priority??
you are a much more relaxed person than I

 

My good friend's a locksmith. Once he gets back from a lockout he'll have me back in the car in no time. Looks like I'm playin' with the multi meter.

 

I use to be able to break into my old car in about 30 seconds. I'm glad I've never had to try it in the lancer yet (knock on wood).

I just had another idea.... could just go directly to the head lights, and find the power wire there that turns on with the switch... but I think thats taking the wiring to an extreme, and ou'd have to run the wires all the way back inside.

 

I'd like to stay on one side of the firewall, thanks.

 

You can tap into the fuse box for this:

Thanks ya muchly.

 

does this go for anything with 12v power?

 

Ended up using a green wire with white stripe that comes from the dimmer and also is switched along with the lights. Thanks all.
