2004 interior lighting problem please help!

I attempted to do an interior LED swap in my 2004 Terminator. Everything went fine until I accidentally broke the flimsy connector for the dome light bulb. Then no bulbs worked except for the dome light. But only when I turned on the passenger map light, the dome light would turn on and off instead. I bought a new lamp assembly, and moved the bulbs over. Now the problem followed. I did a little extra troubleshooting this time. If I leave the passenger map light on, the dome lamp will work exactly as it's supposed to. The drivers side still doesn't work at all though. I opened the trunk, and that light works exactly as it's supposed to as well. Does anybody know what to check for this time? Anyone had this issue and know what the problem is? Thank you!

Yes I believe I know what's wrong. When the repair was done to the dome light I suspect that two of three wires were swapped. This reversed the flow of current which creates a number of problems. LED's don't like it when the positive and negative are reversed. In addition, because of the way the system is wired, the power is back feeding from the vanity mirror (power coming into the dome light assembly via the ground).

It's actually easy to see on the wiring diagrams.

If interested in getting a set for yourself I may be able to help. PM if interested.
Vanity lamps work as they're supposed to as well. Just checked them
I didn't do any repair to the wires. Just replaced the interior of the dome lamp assembly
