After decades of heat, age, and vibration, the original wiring harness often becomes brittle, cracked, or develops broken wires that prevent the dome light from working properly.

This replacement harness is manufactured with factory style connectors, original color-coded wiring, and the correct wire length for Standard Cab trucks. Simply unplug the old harness and plug in the new one for a hassle-free installation with no cutting or splicing required.

Compatible with both original GM dome light assemblies and new reproduction dome lights, this harness restores reliable operation while maintaining an authentic factory appearance.
