Does anyone have the computer pinouts for 2001 5.3L truck motor? Or any other wiring diagrams for it. I tried doing a search but can only find camaro pin outs

This is from a 2002 silverado 5.3 (I cant recall if the first 80 is the blue or the red, but you can figure that out real easy)

You can get all the pinouts from MOTOR or Mitchell's at the local library.
Any year, any engine.

Thank you so much. I tried going to the library but they only had the cheap service manuals with the accessory pin outs not the main engine harness. I tried using the 01 camaro ones and they were close, but not close enough.

the colors are missing on the blue plug from 51 - 80,do you have the rest of the colors you can post?thanks

I never wrote the colors down, But I have the complete wiring diagrams for the motor, and where the wires from the blue and black plugs go and a diagram for what the wires going to the underhood bussed electrical center go to. I tried to post them but couldn`t figure out how so if you want to PM me a e-mail address I can send you pdf files of them.

gnturbo

sweet...my email address is :gnturbo@hotmail.com,thanks a bunch,I have the harness apart and spread out as we speak

gnturbo
