Powertrain Control Module Connectors

The PCM is an engine and transmission controller module all in one, if the vehicle is equipped with an automatic transmission. The PCM uses four wiring harness connectors to receive and send engine and transmission data. To ease assembly, the mating wiring harness connector is color-coded. Each module connector cavity has its own unique color identification stripe located on the outside of each connector cavity.

The PCM module utilizes four wiring harness connectors as described:

Connector Cavity A is for Power AND Ground (Black)
Connector Cavity B is for Engine Side (Orange)
Connector Cavity C is for Headlamp AND Dash (White)
Connector Cavity D is for Transmission (Green) If equipped

NOTE: Connector Cavities A, B, C, And D must be connected prior to battery connection and ignition key on to avoid setting erroneous controller fault codes. It is also recommended that cavity A connector is made prior to any other connectors.
