There is one thin wire right under where the + lead goes to the starter, I would tell you what color it is but I don't think it's had insulation on it for about 10 years and I'm just guessing by counting the sludge rings around it.CK5

Whats the wire right under the batt terminal on the starter?

Starter solenoid wire. It used to be purple, and comes from the park neutral switch, which is fed by the ignition switch. Kinda important for reliable starting.
There is about 3" before it goes into the loom of doom and almost all of it is exposed and not even wound anymore, just strands of raw wire. Fock, this is why I never work on my rig, now I'll have to cut sh!t back so I can fix it and I bet I find more disaster. Can o'worms comes to mind.
Does this wire go to the same lug on the starter as the battery cable or is it on the small terminal closest to the block? If it's on the same lug then that is the hot feed wire up to the junction block on the firewall and there is a fuseable link within that wire within about 6" of the end of it near the starte. If the wire goes to the small terminal closest to the block then that would be a purple wire from the ignition switch which only has 12 volts while in the crank mode.
No it's not the same lug as the batt cable, seperate lug right under it.
I can't understand how it's doing anything the way it is but after my Blazer gets warmed up (bitch to get started when cold) it will fire up instantly.

So are you talking about this one circled in red? If so that is the hot wire to the starter from the solenoid after the solenoid is energized.
There shouldn't be any wire connected to what you have circled in red.
There should be your positive cable from the batter connected to the top lug, along with power supply wires for the truck, and a single wire connected to the inner middle lug. That wire energizes the started to start the engine.

I think he is talking about the one i have circled in blue, so, two wires go there. the main big cable to the battery and another smaller one. That one goes up to the little isolater block thing up on the firewall above the distributer. Its pretty much what feeds all the power to everything on the truck!

if any of you read it. he is interested in the one highlighted in green. it's the ignition signal wire that tells the solenoid to engage the starter.
Yes that one circled in green, I'm going to unbolt it, slide some shrink tube on it and heat it with a small pencil torch. I should be able to get one of those in there with out causing too much heat too close in. Hopefully it's salvageble because I really don't want to start cutting into the loom or I'll have the entire rig down to the frame by the end of the day.
If it was the purple solenoid activation wire,it comes out of the fuse box on the drivers side--you coud snip it there and spice a new peice of wire in,and re-route it so it dont have to be inside the original harness..I have removed that metal conduit the starter wires go into on many 73-87 GMs and cars,the wirse often get roasted in that tube and burn up when they short out...I put the fusible link wires on a junction block and run them right to the positive battery terminal--that way I have only a battery cable and the purple wire left at the solenoid...had too many wire fires from them burning on the exhaust manifold ,once I put the wirig back to the way GM did it up until 1972,I have had no more wiring troubles..it was stupid to put wires in a metal tube an inch from a exhaust manifold & pipe,and not expect them to melt!..
