there is only 7 wires that are needed to communicate to the pcm, I have the schematic at home, I can look at it when I get there tonite unless someone here has the pin numbers of those 7 wires, actually only one is the data wire, two were power wires, and I think the rest were grounds....
Should be, you can use an ohm meter and ohm out the wire from the ALDL port to the harness, again, I can tell you later, I know the hots were like RED 18 & 22, I think the data blue 1 ect, I don't want to give you the wrong info now..

Thanks Moe! If you don't mind looking when you get home i know he would appreciate it!
Do I need to test all 6 or just the Data Link wire?
