2009 G55
Truck won’t start… F2 Fuse Box F8 Fuse is Hot (burnt red/yellow wire)

LTLFTP - thanks for all the help in the past with my CL63. I have since upgraded to a 2009 G55. After installing a seicane (android) head unit and factory amp r&r, a couple days later my truck wouldn’t start. I thought the battery died. Bought a new one, no luck starting. I’ve heard the starters go bad on these trucks, so I replaced that, No avail. I then went on the hunt for anything out of the ordinary. Noticed both brake wear sensor grounds were toast. Replaced (twisted them back together) them and the truck started. Moved it to a better location, and “correctly” addressed the issue. Went to start and nothing again.

How is the breaks wear sensor associated with the starting circuit? How is the seat fuse in the title connected to the starting system? Below are photos and videos of my current situation.
