Sorry to hear such bs. I would put some cheap headlights on and trade it in at this point.

That has all the wiring diagrams they will need. Remove what isn't working and wire in new. If the reverse signal is working on the trailer harness then jump that to the reverse lights.... Done.
Use interior trigger off of switch to trigger new relay patched into main harness in a pillar. Done.
Problems. Solved.

Well I talked to the actual shop and they said it's because of the HID's I had in my reverse lights in the tails. Apparently the amperage is around 7 and mine was around 40. It fried the wire going from the reverse lights in the tails to the BCM and also messed up the BCM. So they said I have to bring to the dealer and change out the wiring and the BCM and get it reflashed. Sucks so bad. Debating whether to fix it and sell it or trade it with the problem and let the dealer fix it and let him give me less for the vehicle...

Wow that sucks at least they narrowed down the issue but frying the BCM is not good. Out of curiosity, do you know how much it'd cost to have the dealer fix the issue with the wiring and BCM? For me that'd be the determining factor. If 1,000 or less I'd be tempted to just fix it. If more than that I'd be tempted to trade her in and move on with life.
