Step 1 — Remove the Front Bumper
- Remove all 10mm bolts, pop rivets, and smaller fasteners holding the bumper.
- Take your time—don’t rush. There are a lot of hidden clips.
- Once loose, disconnect the front sensor harness to fully free the bumper.
- Set the bumper aside carefully.
- Remove the black lower wind deflector.
- Remove the black bracing behind the bumper ends (only the side portions).
- Keep track of bolts; you’ll need every one later.
- Move the red pigtail → socket #11
- Keep the black pigtail → socket #1
- This makes the fog lights activate when the headlights turn on.
- Attach the relay so the lights trigger from the headlight circuit but pull power from the battery.
- Connect the relay and harness to the passenger-side headlight connector.
- Plug it all back into the headlight assembly.
- Route the harness across the lower crash bar and near the transmission cooler.
- Secure everything with zip ties so nothing rubs or moves.
- Pull up the left and right bumper ends near the wheels to access the vents.
- Wedge something (wood block, trim tool, etc.) to hold the bumper up if needed.
- Remove the factory vent covers.
- Install the Tremor lower vent panels in their place.
- Trim the alignment tab on each fog light so the H10 connector fits.
- Go slow with a razor blade.
- Slightly bend connector pins outward for better fitment.
- Connect the H10 plug in reverse polarity (upside-down).
- Tape the connection to secure it.
- Position the bumper close but don’t mount yet.
- On the touchscreen:
- Turn AUTO off
- Switch headlights to ON
- Confirm both fog lights power on.
- Check relay click + battery draw connection.
- Reconnect sensor harness — lock the gray securing bar.
- Reinstall bumper and all bolts in reverse order.
- Confirm clips, wires, and sensors are secured.
- Clean fingerprints/oil off the bumper.
