I'm running a one wire set up,so i want to use the left over wires that aren't being used,am i correct that the white wire is a keyed power source and the red is live all the time?i'm just not sure.sorry my aftermarket harness has a white exciter/trigger wire instead of the brown oem wire.

the brown wire (your now white wire) is a key on power but it also sends power to the charging light in the dash as well as has a resistor in the wire coming from the ing switch from what the wiring diagram shows which I was looking at. the red wire will be battery power all the time. I hope this helps

hmm it's strange the wiring harness didn't say anything like that i used all gauges and no warning lights so i guess I'll have to wait till i fire the car to see how much power is @the white wire. thank you.
