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
