A new message to me, when I went to backup today it said rear backup lights unavailable. I then put the vehicle in reverse and engaged the parking brake to go look. Sure enough I have no reverse lights.
I'm going to try jiggling the reverse light wire under the dash tomorrow (goes into the main connector to the BCM) since it might be that. Earlier in the year when I attempted to install the mopar hitch and wiring harness for towing there was a step where you needed to remove the reverse wire from the connector to splice into a new wire. I tried hard and could not get the wire out so I may have damaged it or the connector in the process. Hopefully not though. It was good for the past 6 months. I bet a dealer wouldn't even attempt to replace the connector and instead would say to replace the whole wiring harness (the main harness for the car) at a cost of probably like $5000.
It sounds like something happened with you Mopar install and the wiring splice has gone bad.
I would check for corrosion or the splice being grounded to the body.
There is such a thing as repairing a connector, Your dealer should have an electrical geek who likes to do that kind of stuff.
They wouldn't replace the main harness for this kind of issue, there is a short harness that plugs in somewhere else to the main harness they may replace worst case.
Dealers definitely don't want to do the whole body harness replacement.
Also, just a word to the wise, MOPAR parts only carry a warrantee for workmanship for install if the dealer installs it.
What I mean when I say that is if you installed a MOPAR part and the vehicle has a failed component down the road due to the install, the warranty won't cover it for sure.
If the dealer had installed it and the issue came up later, its their problem to fix and its warrantable.
