Progress has been slow. I've found a good SM465 PTO, I've been working on the hydraulics slowly but surely, but mostly I've been worrying about trailer wiring.

Rear lighting back in place and with sufficient slack to let the bed tilt fully

Bulkhead connector I'm mounting to the firewall for all the trailer brake wiring

You may notice some other terminals in the background - I'm tapping into the factory harness at the rear harness firewall connector and the stop lamp switch, replacing the terminals and using wire from another harness I cut up, so in essence it will look as if the factory installed the plug in connector for a brake controller inside the cab.
