I prefer the ultra cleanest install I can get. and I've never liked how the wipers came out of the engine side of the bulkhead. I always thought it would be a whole lot easier to disconnect the engine as a whole from the bulkhead. Besides that, Mike is considering doing a remote mount wiper since the firewall smooth sheet he made required a wiper delete. So I moved the wipers over to the lighting side.
Speaking of ultra clean.. Here's what I did with the rear lighting harness. I included the fuel pump wiring and the stereo amplifier wiring and the gas gauge wiring right into the same harness. One harness disconnects the entire rear of the car. Nice.
The former fuel sending unit ground was ran through the roof of the car.
So here's the leg bone being connected to the hip bone again.. the entire interior had to come out (less carpet) for the new lines to be run and the old to be removed. There were powers and ground running down the passenger side for the vintage air and speaker wires.
