Engine wire diagram
 

Does anyone know a reliable place to download or get a copy of a wiring diagram for the engine wire harness on an 04 and 00 5.3 silverado 1500?

I have some somewhere. Let me look thru my photobucket.

Why would you need that if your the fastest truck ever ??? :punch:

The fastest truck ever g

The fastest truck ever got wraped around a telephone pole that wouldent move out of my way. Now the motor is going into a 2000 short bed single cab

Its not working right on my phone.

When i get to some internet on the laptop ill post up the pictures and you can save them.

What exactly do you need?
I have the pcm pin outs and also the fuse box connector pinouts.

Thank you so much nonnieselman. Both would be awesome if you could. I put an 04 motor with an 04 harness into a 00.

Found a copy of the manual here
99-02 cable style PCM is listed here.

If you used the 04 harness With the 04 PCM then I will Suspect you will need the Fuse block Pin out as well...

This guy has some wireing info for both the 99-02 and the 03-05 PCM harness
