Heavy-Duty Power Window Harness

1973-91 Chevy & GMC Truck

Product Details

Upgrade your power window harness for better power delivery to the window motors for modern day speed and reliability. The heavy-duty harness draws power directly from the battery compared to the original wiring that draws its power from the window switch. Harness has separate relays for up and down functions on both front doors. Comes complete with everything needed to splice into the truck's wiring and works with factory window switches. Installation instructions included.
