I discovered that part of the Wtec III wiring harness for the transmission was accidentally thrown away last summer in preparation for an auction.  The missing harness section included the female main communications port connector, the three male 32 pin TCM connectors and the round touch pad shift module connector.  If anyone has an idea where I might locate a Wtec III harness I'd appreciate hearing from you.  Otherwise I'll have to buy the connectors separately and configure each circuit using a schematic.
