12v when started?

[AiR]

MY alarm needs a 12v signal when the car is startedc but i dont know where one is it says oemthing about a oil lamp inside the dashboard but i dont know where it is does anyone know? also is there a 12v on the fuel pump when it is started?

there are two different 12V lines that go to your stereo.. one is constant, one is ignition... if you unplug the harness, you can find the two 12v lines with the car running, then see which one shuts off when you turn off the car...

At the ignition harness, the black/white wire is on when the key is in the ON position (regardless of weather the engine is running). At the stereo, the switched 12V is the blue wire. Make sure to test all this tho, your car may have been hacked up or something and you could fry something. I dunno if this helps, but here is all the wire info you (should) need for installing it. BTW this list is for 1995/1996 Eclipses, talons are most likely the same:

i know about the ignition switches but i need the 12v only when the engine is running. not just when its on the ON position. i think that my alarm is messed up anyways because i sat inside my car with the alarm on and started it then manually plugged the wire into a 12v when the car started and it still didnt work. damn alarms.
