Taillights/ Turn Signals not working

[ChrisLifts]

Long story short, I was an idiot and disconnected all of the rear wiring without labeling anything when I stripped the bus interior out. I have reconnected everything based on photos I took and the wiring appears to be connected properly, but the brake lights, turn signals, and reverse lights don't work. Everything up front is totally fine. I can't find an electrical diagram anywhere online for my bus. Ideally, I'd just pull 80% of the wiring out that is no longer being used and run dedicated wires to just the 6 lights in the back that I plan to use. 6 made up of 2 brakes, 2 turn signals, and 2 reverse lights. Problem is, if I trace the wires they just go into that giant snake all the way back to the fuse block area and I don't even know if I would be tracing the correct wires.

Bus: 2004 International IC CE200

Any advice appreciated!

Tracing wires

Others may have different ideas, but the way I traced wires was I took a long jumper wire with alligator clips on each end, clipped one end to the wire in the back I wanted to find up front, the other end to one lead on a volt-ohm meter and probed wires with the loose lead until I got the continuity beep. Now I've identified the wire up front that's the same one as in the back. Label them somehow, and move on to the next one, etc, etc.

Have fun, and good luck!

BCM....look at you J2 connector, that is where you lights are supplied from. Page 14 I believe

Worst case, run new wires. Best case, you can figure out your color codes. Don't know how happy you chopped
