Ok, we are hooking my LT1 up to the bench dyno. Now we have overcome all obtacles except one. To tune the OBD2 PCM it has to be installed in the car with power. However the engine and wirig harness is on the dyno and I dont want to tear the inside of my car apart taking out the obd2 connector from under the dash and the rest of the wiring.

Is there a way to connect directly to the PCM bypassing the OBD2 connetor?? Or will I have to go to a junkyard and find an OBD2 plug connection as well as the PCM side plug and rig up some sort of cable??

I need to be able to datalog as well while its on the bench dyno so we can tune part throttle air/fuel too.

I need help ASAP !
Thanx!
