Rear 12V Source

This is a 4th Gen thing bit since my truck is 6.4 gasser, I'll put it here.

I am looking to power a repeater for trailer TPMS system. My truck has the Aux switches, and I read that there is a Batt +, and Key + run to the rear ready to go. I fished around and think I located the suspects. There is a red/white, and pink/yellow terminated back there. Before I start probing, has anybody used these wires and can confirm wire colors???

Try the upfitter guide on the Ram website. Good wiring info .

Thanks, I had looked and totally missed the section with "blunt cut wires". Looks like I have to install a jumper under the dash to activate those circuits.

I was a little confused by the schematics, as in one place it says to plug in the jumper, and in another it talks about cutting wires, so I emailed Ram Bodybuilder to verify the procedure. Much to my surprise, I got a quick response saying just install the jumper. I did that this morning, and those circuits are active and the pink/yellow checked out as key power.

Terrific. Once in a while, things just work out the way you planned.
