making wiring harness from scratch

Super T,
you can use the old plastic, just pull the brass and go to www.riwire.com and get new brass either crimp or solder. I think ours is listed under the Ford blades in components.

Read post #28 in this very thread.

Damn, I missed that 28 :-) Thanks, that helps a lot. I plan on a military 24-pin twist-lock instead of the factory 3x8 pin connectors. But the actual device connectors will be a huge help!
