When someone bumps they are pushing your thread to the top again so more people will see it. Just a freindly way of helping out

Its possible you have a wire chaffing before the harness in the back causing a dead short?

Doubt that wire damaged under truck. Fuse 8 feeds part of the light switch that energizes parking light relay. This relay is located with the keyless entry relays where ever that is.
