A wiring harness for lights on a Ruff Rax bed rack, for 1500 and 2500 series trucks.

The loom runs the length of the bed rack with take-offs along it, so light wiring is carried inside the rack structure rather than taped along the outside where it chafes and looks like an afterthought.

Two pounds. Roof rack harnesses are a different part — check which rack you are wiring before you order.
