I bought a pcm off of ebay, so I could save my old one, when I get a mail order tune. The listing said it was from my same model truck, 2000 Silverado 1500 V8. The case looks different then the one in my truck. I didn't pull the wire loom off, but it looks like it would fit. Are all the 2000-2002 truck pcms the same ?

 

I have a 2000 Sierra and there is no way that would work. The 2 set of clips (red and blue) that clip into the PCM and have a screw that tightens in the center. Also the PCM isnt covered in plastic, its metal.

Im not sure about the 03+, but I know the 02s are the same

Thats not the right PCM, sorry

 

I have a 2001. There's not 4 plug ins. Just two Long ones.

I have a '00 5.3 Silverado 1500. The PCM has a metal cover, not plastic, and has two long side by side sockets for the PCM harness. Blue is on one side and Red on the other...

 

Yup just like that

Thanks guys... I guess If I would have pulled the wire loom, I would have seen the difference. The one they sent me is actually black metal. The auction had a picture of a different pcm, they probably just sent the wrong one.

 

the one you have is for the old 5.7 motors. they used them engines in some of the burbans and tahoes for a while. i bet you got one of them unless you just plain got screwed.

 

Does anyone know the correct part number ?

 

try p/n 12200411 on the gmpartsdirect site...2001 PCM and should work for your 2000. Around 135 plus 200 core if you want new
