I ended up mailing BP my ECM and TCM today. I tried to pull codes with a scan tool today and the scanner powers up but wouldn't link. Bill said the TCM is the first link up for the scan tool and he seems to think the place that sold me the setup may have just sent a non matching TCM. I hope this is the case. I had constant and switched power at the TCM connector.
