Hi guys,
Hope you are all well. Strange issue - I have an 85 SC. Whenever I mount the logic module in the kick panel the car will stall and not start. Apparently when the logic module comes into contact with the chassis it shorts out and the car will not run. Tried different logic modules with the same result. It appears there is a short somewhere in the harness. I looked at the wires going into the LM and it seems OK. Any ideas where to look and troubleshoot?

Thanks, Ralph
