  • Pair of windshield light brackets
  • Wiring harness

  • Relay
  • Zip ties
  • Ratchet with socket set
  • T30 Torx screwdriver

Pro Tip

Depending on the the windshield light size and the bracket, you may have to bend your radio antennae.

Step 3 – Connect the windshield light harness

Remove the windshield wipers and the wiper cowl. To do this, there will be 13mm nuts on the bottom of the windshield wipers. To remove the wiper cowl, undo the four T30 Torx screws at each corner, and the four plastic tabs on the center screen. Starting from the driver's side light, route the wiring harness across to the passenger's side light and then under the hood to the battery.

Install and mount the relay for the windshield lights to the side of the engine compartment. To power the lights, you can use a splice connector to connect them to your high beam headlights. The wire for the high beam is white and grey on the passenger's side; white and green on the driver's side. The windshield lights will come on whenever the high beams are turned on.

Before you test your new windshield lights, make sure that the ground wire is connected to the Jeep's chassis. Then start the Jeep and turn on the high beams. Adjust the windshield lights as needed.

Pro Tip

To access the high beam wires on the passenger's side, you'll need to remove the air filter. The air filter is held down by four tabs that are simple to pry off.
