Installation Notes and Tips

Verify the rear left position and connector style before installation. Inspect the mating connector, terminals, and nearby wiring for corrosion, bent terminals, or insulation damage before connecting the new harness. Confirm the harness routing follows the original path so the lead is not stretched, pinched, or exposed to moving suspension components.
