+12V in the trunk?

[scorp965]

I am looking for switched +12V in the trunk, does anyone know if there is a pre-existing source (cd changer, antenna, etc.), or will I need to run a power wire back there, from the ECU location?

This is for a reverse camera, but I don't want to wire it to the reverse lights.

How about the 4-pin phone harness connector? I don't know if all cars have the prewire, but there's hot, switched, and a ground on that connector in the left front corner of the trunk.

isn't there one on the antenna harness.

yep, the one on antenna harness powers-on with the switch. if i recall there are 2 positives, one stays on with a key, one is a pulse.
