Wiring Harness Service

Prevent corrosion of the wiring terminals by applying
skin-over grease to the inside of all harness connectors
whenever the harness is disconnected.
Always disconnect the battery cables, negative (–) ca-
ble first, to prevent possible wiring damage from short-
outs whenever working with the electrical system.
