You should be able to get the pinout diagrams at www.alldatadiy.com i have a subscription there also and love it.

will go look after I found food. Thanks for that info

which car do you have?

97 bonneville and 2000 blazer

what I'm having to do is repin my 96 harness and add in the tranny plug. But at least this way every thing will match up. I have the pcm plugs repined all but to wires that don't match up. But I'm done for the night, I'll keep going sunday

ok all the codes are gone. So rebuilding the 96 harness was the key. I do have one problem when I put the tranny in gear my traction control comes on. If I unhook the two traction control wires then all is fine but the dash light is on saying traction control off. I even tried swapping the two wires but got the same. Any ideas???

Thanks

also this web site has the pcm pinouts. It'* for fiero'* to different gm computers but the pinouts are the right ones
