I pulled the unit out today and the truck wiring didn't match any of the diagrams until I found your information which appears to be exact. A little testing with the digital multi-meter tomorrow should get it fixed after I replace the blown 20A fuse for the battery feed.
No big deal. Constant (solid yellow)just not hooked up right. Red and yellow just might be backwards. Acc VS constant.
As for the lighting up and such...he probably hooked up the illumination/dimmer wire. Orange or orange/white, it's labeled on the wire. If you see those hooked up...cut them! I have NEVER hooked them up, they can cause a lot of issues sometimes.
Remember...those lines are HOT, make sure to cap them off

Take a picture of what you do have in there for me and I'll see what I can do
