I have a DMM, a fair amount of electrical knowledge, and a test light that I'm not sure I've ever used. I bought a 2000 4runner limited 4x4 and it has some electrical gremlins in this circuit. I have the FSM for my vehicle, but didn't see a pinout anywhere in it.
Thanks in advance for the help!

Test each pin on the 3C plug for continuity. When I know what pin carries the short, I can go circuit by circuit to see where it goes. There is no easy list. Two I found are 10 is key light and 7 is rear dome. Note the wire color to double confirm. 7 and 10 are both blue-yellow. Page 27 shows all the module does is connect Pins 4 through 10 to each other.
To get the numbers, see pin out on page 26 here. Concentrate on pins 4 through 10, excluding Pin 8, which is the incoming from 1f that feeds 4 through 10, which should show 12V+ full-time if battery is connected and DOME fuse intact:
