1985 D150 "Mr. Curtis" race truck with a 2015 6.4

Ha, best idea ever to do the above. Because look what was super easy to do yesterday:







I made a bracket for the BCM and riveted that bracket directly to the heater box. Mean but it works for now:







Then came the "pita but not hard"-part.
The engine room harness has to pass through a 2" hole in the cab.
It's 2" because i am re-using one of the OEM bushings and it was a pain because i had to make a metal sleeve so i could pass all the wiring through that bushing, which is essentially a bit too small for what i was asking it to do...

Remember to split the sleeve so you can remove it later:



Then use a bit of silicone spray...



... and needle nose pliers to do this:





Aaaand after doing it twice, because i had the bushing on the harness the wrong way and realized it after finishing the last connection, ta daaaa:



Now i can shoot that 2" hole in the cab and continue...
