    Thanks! LOL.
    Im figuring most of it out, but I’m still lost on this one. It comes from the same wiring harness that has the oil and water temp senders. Idk if it goes to the choke, or to the flux capacitor. LOL

    Often connectors are meaningless.. I've been working on cars since mid 1960s, I dunno what it is.

    Using a wiring diagram, circuit is determined by color of wire.

    I’ve been looking at a few. I’m going to have to trace the wire back a little, I can’t tell if it’s solid red, or a purple, or brown because the exposed area is dirty.

    I remember seeing something like that going to air cleaner or the vacuum switch bolted to the valve cover...I think. Its been a lot of years since I saw it

    LOL, yeah the mid '70s were loaded with all sort of contraptions. I usually tossed the mess in trash can & connected like the 1967 models. Those ran fine without the snake pit of wires, vac hoses & connectors.

    Brown was color used for outside lights, park, side marker, license etc.

    Oops. Did something weird there.
    I’m honestly thinking I might just hook up whatever I can figure out, fire it off, and then see if I even need the rest. Might be some a/c wire that I’d never ever need

    I have a connection just like that on my 74 Comet that goes to my electric choke, there is a wire that goes from the choke to that connection.

    That makes a ton of sense, and I have an inkling that may be the case. I was going to get the battery hooked up and test it for power with the ignition on this weekend. The placement, and length of the wire seems to point towards that very thing.

    Supposedly the choke wire is black/white.

    In any case, choke feed connects to alt stator, no voltage unless alt is charging. Choke release only operates with engine running. Some vehicles routed choke power through a multi contact oil pressure sender, again no voltage unless engine running.

    Of course engine could be making a Blam, Blam, Blam! Noise.

    Hey Joe, can't figure out why the choke isn't releasing...:slap:
