Hello! I hope I am posting this right. I am looking for information pertaining to a base Pontiac Bonneville. I need to find a wire that is hot after the car has been started under the rear passengers seat.

I want to activate a relay only when the car is running, but I do not know what options are under the rear seat. While I would prefer a started hot, I would accept an ACC/Run hot if that is all that is available.

Thanks!!!!

i dont think you are going to find anything under the rear seat even in the harnesses running into the trunk, but here is the wiring for the ignition harness if you wish to run from there.

12 Volts	orange (15A)	+	ignition harness
Second 12 Volts
Starter	yellow	+	ignition harness
Second Starter	N/A
Ignition	pink	+	ignition harness
Second Ignition	white	+	ignition harness
Third Ignition	N/A
Accessory	orange	+	ignition harness
Second Accessory	brown	+	ignition harness

Well I was thinking maybe the XM Radio Receiver, although I don't know if that is always on or not. I assume it is. I don't use it, so I guess I'll pull out the meter and take a peak at it.

Thanks for the ignition harness info though, that will be my backup since everything is going in my trunk.
