New wiring for our ‘67 B’cuda

Not sure what you need or want at this point.
We've offered photos, factory assembly diagrams, wiring diagrams.
As Redfish wrote, there's only a very limited number of places each connector can reach, and the majority of connectors are unique to the item they join.
Maybe the best thing is to post up photos and questions on specifics when you run into something that's not obvious (to you). I've found cudaAl and others pretty helpful when I had such questions.
