How To Install Replace Taillight Harness Junction Block Silverado Sierra 99-09

This replacement tail light Combination Junction Block is just what you need to get your GM Full Size Truck in good working order again!

This junction block connects the rear body harness to both Tail light harnesses and license plate light harness. It is mounted on the rear frame rail behind the rear bumper. Due to this location, it is constantly exposed to the elements of rain, road debris, salt, & snow. Since it is electrical, this can cause it to corrode and then stop functioning. Many Tail light electrical problems are because of this junction block malfunctioning.


  • Replaces dealer part number: 15304995
  • Direct replacement
  • Built to strict quality control standards
  • Mounts on rear frame rail

Note: This GM Full Size Truck tail light combination junction block makes a great replacement and could help solve many electrical problems!
