I need to find a wire in the column or behind the dash that gets +12v when the truck is in reverse. 96 4x4 4.0L Automatic tranny.

I could probably go through everything with a meter, but I can't get the truck in the garage to work on it & I can't stand the heat outside long enough to figure it out.
I know someone will have the answer

Reason for needing to find this wire?
I need to tap into the reverse power wire to activate a backup camera input on an in dash dvd.

Rather not tap into the reverse light wire & run it up in the cab as it's getting hard for me to get under the truck

If all else fails I'm gonna have to use a mini switch on a 12v source, but I'd rather not have to remember to flip a switch when I'm backing up if I don't have to.

From what research I've found so far, it looks like there's a black/pink wire somewhere near the e-brake cable. I haven't made it out to test, but could this be the correct wire?

 

You should be able to find the Black with Pink stripe between either at connection 146 (LH rocker panel) or connection 340 (under the driver seat where it goes through the cab to the rear harness).

 

The BK/PK hot-in-reverse feed is in the large bundle of wires that go through the triple bulkhead connectors in the firewall near the e-brake pedal. There should only be one wire in that bundle with the BK/PK color code.

 

Thanks guys,
Looks like I'm headed in the right location
