Here is what mine looks like. I'm glad you posted this. It made me look and see. My switch wire is draped up over a vinyl side piece foe the windshield. I can see how that wire can easily be broken. Also after taking these photos I discovered
1 that Phillips head screw backed off
2 that bolt for the bunk backed off. I suspect that is a self tapping.
Btw. Only 1500 miles! So I'm glad I'm handy because there's always gong to be something else to fix.
