TBI wiring experts

[b454rat]

I'm looking for somebody that is good with wiring and ECMs. I have a 6299 which is the same as 7747 in my 92 Blazer, switching to a 7060, so I can run a TBI454 and 4L80. Got the wiring diagrams for both, and think I have them swapped over on paper. There are some pins that I can't find, and that won't directly crossover to the 7060 pins. Anybody help me out and double check this???? Want to get the swap going, I think my S-10 is on it's way out....

File is too big for an attachment..

Did you go over to the gmecm section at diy-efi.org?

I'm suspecting the difference is in the wiring colors, so comparing the two diagrams should work if they are both factory.

Are you using the GM wiring manuals? If not, things like Haynes are typically pretty close to correct, but usually just a bit too generic for all the wiring.

That is where the 7747 came from, not sure on the 7060 one. Had a guy on 454SS site gimme that. Haynes is OK, but trying to find what pin goes where doesn't help, they don't list what ECM is being used. Gonna go tomorrow to a garage that has that stuff, if not the stealership.....
