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 passenger compartment.
Replace wire harnesses with the proper part number replacement. When splicing signal wires into a harness, use wiring that has high temperature insulation.
Consider the low amperage and voltage levels utilized in Powertrain control systems. Make the best possible bond at all splices. Use rosin-core solder in these areas. Refer to the Wire Harness Repair graphic.
