Oh yikes, maybe that's what was preventing my battery from charging..... But my alternator tested bad..... Well I know now either way. Where should I connect the choke then?

And yup, that's what I'm seeing. The A terminal has 2 yellow wires coming out of it, one of which just ends about 2 inches out in a little single plug with nothing plugged into it, and the other one of which snakes down into the main harness. It never comes out, and I can feel that it and several others are just looped around in there. And the 3 wires that do come out are all accounted for.

My charging system has worked though in the past.... I've always thought that the whole thing is set up kind of screwy, my truck's had so many amateur mechanic owners, including me, but it seems like I'm the first one in 30 years that's at least cared.
