I am trying to get my ScanGauge II to work (it plugs into the OBD  connecter) but "pin 19"

It gets, it,s fire from the ecm,you may have bad harness coming off the ecm to obd connector,or the ecm is going bad.

TST is correct. However I've had a few cases where the fuse for the cigarette lighter/accessory port was blown replaced it and the OBD worked.
