Bulkhead connector ideas?

Will be using a billet connector from painless - one for the engine where it's hidden, another between the outer and inner fenders for the lights, horn, fans, etc. The goal is no visible wires.

Going with no connector eliminates points of failure, but if the connector isn't a 40-year-old piece of garbage it wouldn't be a problem in the first place. If you go this route, you don't have the luxury of being able to just unplug it to pull the engine.
