No wiring diagram

If I read you correctly, this was a hack wiring job bypassing the factory wiring. I would return the wiring back to factory, even if you have to run new wire using the schematics. God only knows who did what, I have always found it easier to remove the hack wiring and replace, as you will go crazy trying to figure out what the last guy did.

Agreed.

If I had to hazard a guess at this point, the marker lights and skirt lights are connected in the junction box to the same hot post. Then, also guessing, there’s a short to ground in the skirt light circuit. Thus causing the skirt light relay to turn on/off in tune to how fast the lights turn on/off, even with no skirt light fuse installed

When I was at my shop last, I pulled it outside and it started acting up. The fuse for the tractor marker lights blew. I unplugged the skirt lights, reset the circuit breaker and carried on into town
