Wiring Harness Service

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

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

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

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