93 to 94 LT1 Conversion, No Comunication Through Diagnostic Port
I converted my 93 Trans am to my 94 Camaro LT1 engine and tranny. The motor runs no problem. However I can not get my laptop to communicate with the T/A through the Diagnostic Port. It has the same color wires going into the OBD1 diagnostic port as the camaro, but no communication. Note I did switch to a different laptop since I had programed it in the camaro. So my question is:
Is the problem with the laptop, or can I not use the 93 port and wireing harness. Note the 94 and 93 connectors on the Passenger side floor were a plug and play.
Also Tuner Cat says it has not communication. The Commlog says connected but gives no information
Thanks

The auto trans is electronic in 94, not in 93.
93s are batch fire, 94+ is sequential.
The brakes are slightly different.
The speedo/dash/wiring is different.
there's more, etc

So, when i hook up the 94 harness into my 93 plugs under the dash on the passenger side, what all isn't going to work correctly other than the DLC? Just the DCL or am I going to have other problems? I cross referenced the pinouts on the 93 vs 94-97 and there are more then 1 so i'm a little worried. I'm going to keep researching but any help would be appreciated.
