Dorman Tail Light Wiring Harness for Silverado

Restore proper tail light operation with this Dorman tail light wiring harness, part number 645-930. It is a direct replacement harness for the right rear lighting circuit on select Chevrolet Silverado trucks, helping address wiring damage without replacing the full lamp assembly.

  • Tail light wiring harness for the right side
  • 4-wire design with 12-gauge and 16-gauge conductors
  • 76.8 in overall length for routing to the rear lamp area
  • Female blade-style terminal with plastic terminal material
  • OE-style replacement for select Chevrolet Silverado 1500, 2500, 2500 HD, 3500, and 3500 HD applications

Product Details

Dorman 645-930 is built as a separate harness assembly so you can replace the failed wiring section instead of the entire tail light assembly. It is listed for right-side rear applications on 2007-2014 Chevrolet Silverado trucks, including 2007-2011 Silverado 1500, 2500, 2500 HD, 3500, and 3500 HD models with 3047 reverse lamp bulbs, plus 2012-2014 Silverado 1500, 2500, 2500 HD, and 3500 HD, and 2012-2013 Silverado 3500. This part cross-references OE number 15824515 for the same application.

Common Problems This Harness Can Address

  • Intermittent or inoperative right tail light function
  • Damaged, brittle, or heat-affected rear lamp wiring
  • Corroded or loose terminal connections at the tail lamp
  • Broken harness routing from vibration or rear-end service work
  • Electrical faults affecting brake, park, or reverse lamp circuits

Installation Notes and Tips

Verify the vehicle year, model, and right-side rear lamp configuration before installation. Match the connector style, wire count, and bulb application to the original harness, especially on 2007-2011 Chevrolet Silverado trucks that use 3047 reverse lamp bulbs. Inspect the surrounding lamp socket, ground path, and adjacent wiring for additional damage before final assembly.
