Water Leakage Prevention
Water from wet areas can travel along with wiring harness and flow into the vehicle through
bulkhead grommets. Make sure the section of wiring before the bulkhead is lower than the hole,
this is referred to as a drip loop. The drip loop will prevent water ingress. If you install wiring into
hinged doors, the point of entry in the door must be lower than the hole in the door pillar. This
will prevent water water ingress into the vehicle.
Joints in the Wiring Harness
If you must join wires use heat shrink sealed, nylon insulated, crimp connectors and ratchet
crimp pliers. The joint must insulated and water resistant.
Wiring Specification
The vehicle wiring harness uses plain copper wire.
