Wiring Harness Service

The control module harness electrically connects the control module to the various solenoids, switches, and sensors in the vehicle engine room and the passenger compartment.

Replace the wire harnesses with the proper part number replacement. When splicing the signal wires into a harness, use wiring that has high-temperature insulation.

Consider the low amperage and voltage levels that are utilized in the powertrain control systems. Make the best possible bond at all of the splices. Use rosin-core solder in these areas.

Molded-on connectors require a complete replacement of the connector. Splice a new connector into the harness. Replacement connectors and terminals are listed in Group 8.965 in the Standard Parts Catalog.
