If I could start all over again, I’d probably go with one of the little Eaton-Bussmann RMTR type panels and pin it from scratch with the metri-pack/ weather pack terminals. It’d be a pain up front, but super compact in the end.
I ~could~ still change gears and go that way, but would be stuck with a few things I’ve bought already.
The actual weatherpack connectors like you show, are super nifty, but I’d struggle to justify it on this truck. Might be good at the taillights for a disconnect option.
For the taillights have a look at the waterproof 7 pin trailer plastic BOXES. They have labelled studs inside, use ring terminals. Easy to disconnect, easy to wire, clean, and easy to add other stuff later (or trailer wiring for that matter) if you're so inclined. I went that route on my 49 and now a few other rewires. Packed the box full of silicone grease as insurance but mounted it inside the frame out of the way, stays clean. Opened it up the other day and it was still like new in there. On mine I also like to replace the terminals inside the bulb sockets just to eliminate one more connection - probably not necessary in a drier climate but here we have a ton of ambient humidity and rainfall, so the fewer connections the better. Places you wouldn't expect moisture to form, form moisture up here - proper heat shrinked connections help there for sure, but I prefer to just minimize that entirely.
