Computers and Control Systems: Service and Repair

Wiring Harness Service
Replace the wire harness with the proper part number replacement. When splicing signal wires into a harness, use the wiring that has high temperature insulation.
Consider the low amperage and voltage levels utilized in the powertrain control systems. Make the best possible bond at all splices. Use rosin-core solder in these areas.
Solder-on electrical connectors require the complete replacement of the connector. Splice a new electrical connector into the harness. Replacement electrical connectors and terminals are listed in the Standard Parts Catalog in the Group 8.965.
