Looks that way! I couldnt find that diagram when I was looking, but the GM service database thing isnt exactly organized efficiently haha

 

No it isnt neither is mitchell or alldata, then again they are just regurgitating what gm puts out there.... I am going to connect it to the post i think it goes to, which i have found a few places that confirmed what i was thinking and get everything connected finally hopefully this evening or tomorrow.... Gotta pull my trans again to fix a leaking pump seal, so that would be the best time to connect the cable to the starter.... Thanks for your help atomic!!!
