can someone please point me to a 12 V ignition wire that is easy to get to (under the dash?). I was told the factory stereo harness has one. I have a 94, if thats the case, what color wire in the harness is the + 12 V?



Im setting up my water injection and I need this, thanks.

 

The 12V should be an Amber or red wire. I think that applies in all cars. Lemme look when I get home tonight, if you don't find it by then...

 

if you have a 'test' light you can just grab the most obvious wires and start testing. You're looking for hot when the key is in the 'On' Position. I wouldn't hook it to a constant 12v source otherwise it'll stay powered when the car is turned off.
