BTS WIRING GUIDE · PRO COMP 76504P

Jeep JK Pro Comp Fog-Light Wiring Guide

Identify the main fog-light adapters and separate halo wiring before fitting this pair to a supported 2007–2018 Wrangler JK.

Start with the exact pair and harness

This reference covers the Pro Comp 76504P pair, listed at BTS as EXP76504P. For 2018 vehicles, confirm JK rather than JL. Match the original fog-light mounts and connectors; an aftermarket bumper can change the required hardware.

The original four-page manual includes a parts layout and one complete wiring diagram. It does not illustrate JK bumper removal or identify the Jeep’s factory-wire colours. Use the applicable vehicle service procedure for access and verify the actual circuits before connecting the halo control leads.

The manual is marked “For off-road use only.” The current product advertisement makes different road-approval claims, so this guide does not promise road approval.

Original parts and wiring diagram

The complete original diagram is shown below with its connector labels intact. Open it at full size to read the small labels.

Match the supplied connectors

  1. Inspect the parts. The manual lists two halo fog lights, one control wire and two connecting wires. Check the supplied parts and connector shapes before dismantling the vehicle.
  2. Isolate electrical power. Disconnect the battery ground before electrical work. Route wiring away from sharp edges, moving components and heat.
  3. Main fog-light connection. The diagram labels A1 as the original fog-light connection and A2 as the 9005-to-5202 converter. Match the actual factory plug to the supplied adapter.
  4. Halo connection. B1 and B2 join the lights to the separate control harness. The drawing labels C as the blue lead to headlamp positive and D as the white lead to the vehicle’s DRL switch. Those are harness labels, not verified Jeep factory-wire colours. The accompanying text describes DRL, parking-light or keyed-power options; confirm the appropriate circuit for your supplied harness before applying power.
  5. Secure and test. Secure the lamps and wiring, reconnect power only after completing the connections, test the main lights and halo separately, and set the beam aim. Stop and check the connections if a function does not operate correctly.
