Bought a nice '92 RS 305 A/T recently that is currently running on a truck ECM. Previous owner said that he was having PassKey problems. I found the PassKey module under the passenger seat, but I can't find the wire harness connector. Manual says that it should be under right side of dash near the ECM. I have the ECM loose, the DERM loose, the Cruise module and the VSS Buffer all loose, but no PassKey harness or connector! I have looked everywhere! Does anybody know where the module would have originally been located so I can properly diagnose this vehicle. Thanks for any help!

it says under mitchell that it is under dash right side also. there is probally 2 connectors there for it cause it says a and b. that usually means 2 connectors. 1 plug has pink-black dark blue black-yellow black yellow gray white-black other connector has black-white purple-yellow orange both should have 8 spots for wires but some not used. hope this helps you.
