I like what you’ve done with the wiring. I started to disassemble our RF harness (from a circa 2012 coupe kit!) then decided against it- but should have done it. I actually sold Ron Francis a new Mercedes back in the 80s. I think his son now runs the business. They’re just up 95 from us in Chester PA. Hard to believe you’re on your 3rd FF5 kit. Yesterday George and I tackled the driver’s door. It’s certainly a 3 dimensional job- fitting the hinges to the frame, fitting the door to the body and finally fitting the door to the door frame! Oh, then adjusting the latch mechanism to the latch.
Good luck on the truck!
