Ok I saw the pinouts somewhere on this site. the PCM and 5.3L from a 2002 4wd suburban with a 4L60E. I am swaping the motor into a 75 C10. the Harness was cut from the junk yard so I dont have the 4L60E connector. The 4L80E im going to install, I have the connector. I need to know what pinouts to splice the 4L60E wires to the 4L80E connector. I also know there are 2 speed sensors on the the 4L80E. I have all the loom torn off and cleaning what I don't need. I know I will need either custom flexplate or torque converter to bolt up and s.w. for the PCM. I saw a post on it but it was for a F body awhile back and for a pre 1998 PCM. I pulled the 4L80E out of a big block suburban. 94-97 body style. I didn't look at the vin but It's a certified gm rebuild sticker on it and it has the original stamping plates on it if that's any help.

My 4L80E doesn't match up to that diagram.
I don't mind wiring it to use both speed sensors.
Most of the wires I can go by the factory pins but #'s E,L,M,S and My wire colors harness side and connector side dont match either. Is this an older style 4L80?

I should add the Harness is out of a 2002 4wd suburban with a 5.3L 4L60 that i am using the PCM wire diagram from.
