Necessary to allow the roof rack to be removed and the cable passages to be sealed.

Traditionally, the wiring of accessories installed on roof racks has involved pulling the installation through the windscreen, between the door apertures and the B-pillar. As part of the evolution of the ARB BASE Rack roof rack, ARB engineers have developed a solution for wiring installations from inside the vehicle to the outside in a neat and tidy way.
Two wiring kits have been developed. One kit is pre-wired with 6 wires (3 circuits) and the second kit has provision for 6 wires allowing for different cables depending on usage needs.

Key criteria during development included:
- Watertight solution for passing cables through the roof of a vehicle.
- Seamless integration with ARB BASE Rack.
- Outlet grommets to suit standard outer diameter conduit sizes of 10 mm (3/8") and 13 mm (1/2").
- High quality automotive wire according to JASO standards (PN 1780400 only).
- Free of liquid adhesives.
- Disconnect kit to reseal and close the roof penetrations when the roof rack is removed (ref: ARB-1780620).
