4. Using a multimeter set to continuity, check the continuity of each wire. If continuity is good, replace the plug, it can only go in one way, and tighten the hold down nut. If no continuity, replace the cable.


The plastic terminal harness, rubber gasket, plastic washers and nut must be removed to withdraw the cable from the body.

1. Mark on the harness the placement of each wire. Use small needle nose pliers to grip the metal terminal end and with a twisting motion, push each one out of the harness. Once the terminal ends are free, remove the washer, rubber sleeve gasket, washer, hold-down nut.
