I think GMpartsdirect.com and I have a couple of more places that have it but can't remember them right off hand .
And yes the harness is part of a forward fog light assembly , so if you don't have fog lights and you want them you get two for the price of one .
My point wasn't about the fans pins - there are several 4wd connections to the pcm. If you switch to a 'vette os you'll most likely loose the ability to have 4wd. If I get bored today I'll look through the charts and see what actually goes where.Originally Posted by HD6.0l
I looked at some schematics and pin 42 and 33 are there in 02 so the PCM should trigger both just fine (2wd and 4wd) .I think GMpartsdirect.com and I have a couple of more places that have it but can't remember them right off hand .

I don't think that would be a problem, as both trucks and the vettes used OS 12212156 in 2002.Originally Posted by jknox

So could I upgrade to an 02 OS and maybe solve the problem of only having one fan relay output.

you can make your own harness http://img.photobucket.com/albums/v7...ring3relay.gif
This works just like the factory harness , A/C on Low (2 fans) , temp reached 210* Low (2 fans) , High temp (over heated 240*+) High (2 fans) .

ok maybe I have overlooked it some where but here goes. I have a 2000 Z71 Tahoe...OLD BODY STYLE....5.7 engine. I got the 05 oem fans and puchased a Nelson harness.....they failed to tell me that their harness was only for the new body style....I can make it work but need to know if there is a pin I can use other than 42 because my blue PCM connector only has 32 pins. Silly me, I believed their plug n play talk. I know that it is only a ground but would like it to be temp operated.
