Give Your Windows Faster Window Speed

Upgrade your power window harness and get better power delivery to the window motors for modern day speed and reliability.

The heavy-duty window 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.

Frequently Asked Questions
Q:How does the power window harness install?

Q:What tools are required to install the power window harness?
A:You will need wire cutters, strippers and crimpers to install the wiring and a wrench or socket to mount the relays. Basic tools will be needed to remove and install the door panels.

Q:I'm having trouble getting the window harness to work, can you help?
A:Start by checking all of the electrical connections, including the ground. Refer to the installation instructions to verify that the connections are made correctly.
