From the looks of the AAC diagram, the brights and the indicator split at the dimmer switch, one light green going to the lights wiring harness and the other to the dash lights. There shouldn't be any other intersecting wires, including at the harnesses, if there are, that should be the culprit. Also can't hurt to check continuity at the dimmer switch just to eliminate the possibility of it being bad.

I'm curious about the 2 brown wires coming out of the "Rear Tail Lamp" pin on the lights harness in the earlier photo. Where does each go, should there be only one wire coming out of it (can't tell from the diagram)?

To combat my ground issues at the bed, I cleaned away paint and rust in a small area on the frame and ran a 12 gauge wire from the frame to one of the bed studs. I also removed both tail light lenses and ran a 4" length of 14 or 16 gauge wire from the bed body to the tail light buckets. Haven't had a tail light issue since.
Single brown goes to the parking
Double brown to the rear tail; i will verify
I did ohm the wires to verify from light switch to each end run For both park and tail

Odd the LED brake lights are bright
No change with the brake switch plugged or unplugged

Best way to check continuity on dimmer switch?
The hi-lo beams work when engaged.
