Welcome to the forum, Check the circuits at the headlamp switch. Can you unplug the connector/s at the rear, for all rear lites. Then use a testlite between voltage and brown wire. The testlite controls the load, if it comes on, the brown wire circuit is shorted to ground somewhere from the test point to rear. I don't hunt the short on a long circuit. I make sure which circuit has the short, then clip the old wire front and back, leave a pigtail, long enough to splice onto, run new wire. I splice temporarily at first, just to see if everything will work.
I used the brown wire as an example, longest circuit. You have to find which wire has the short.
