'91 S-10 distributor problems

[The Big Green]

I had to repo this from someone. The truck had a bad coil (standard round black external coil for most trucks/cars) and it was replaced with a good one, same kind. Anyways, the coil wire from the distributor had a bad connection, and right as I got home it backfired, like a 12 gauge. I don't have power to my distributor, or the hot wire from the truck. It has been a a few months, and I need to fix this. What wire was the hot one? It was a 4.3, now carbed 350, and I have most of the wiring harness, I need to cut this out, or what I dont need. I have a wire, should be it, its on the left side of my carb, right beside it, I believe like a cream color, with a black line. I have blown a few distributors, I don't like the Accels, and Mallory dists. because 1 bad groung, and pow, gone, $100 to fix. I have a Accel street billet, I thought about adding a MSD ignition, and not fixing what I blew.


What wire is hot at dist. when I turn the key on?
