Rear Bumper Backup Sonar Wiring

[joe nv2500]

hello all. I have a 2500 nv "S" model without the backup sensors and wanted to hookup to the wiring if it has been run to the back if it has been run to the back. Any one know if the wiring is back there?

the manual I have, shows the two main body harnesses & I can't see a connection for the rear sonar sensors. My information may not be complete. This is on a diagram for upfitters. Maybe someone else has more complete manuals.

Thanks Vanguy. I crawled under there and saw the hitch wiring and that's about all. There are the 2 taillight wiring runs inside but I'm not sure if they hook off from those or have a separate run or harness of some sort

I will have a look sometime for you, unfortunately the weather is not on my side. The sensors do go off when there is a trail of rain that runs down the bumper or if they get any snow on them. Good thing there is an OFF switch on the dash.
