Pretty sure it is the same as the LS1B.
No it is different. Even has way less terminal pins. I have tried LS1B, V6 Buick, Northstar pinouts as they are all different too.Quote:

The LS1B bench harness I have runs all those PCM's you've listed there, V6-P04, Northstar-P06, they are all the same pinout for bench connections (and of course E54 - LB7).
I just put a P08 on my LS1B bench harness and it works fine.
Blue 60 = Ground
Blue 20 = 12V Unswitched (Batt)
Blue 19 = 12V Switched
Blue 58 = VPW Serial Data
Interesting... I will try again and count the pins on the LS1B Connector instead of the ecm.Quote:

Connecting to this Cavalier one and it back feeds power to the key on circuit.
EFI Connection sells a seperate harness for all these for this reason

My harness had to many wires. I simplified it down and works. You was right as normal... Thanks for the help.
Yeah that's the trick, those four wires I mentioned are common for all those PCM's that look like that.Quote:

I never had the calls for them till recently. Local dirt tracks now have a class for these front wheel drive cars and becoming very popular.Quote:
