Keep your existing controls and wire the LPs properly

If you have already chosen factory upfitter switches, sPOD or Switch-Pros controls, this harness helps bring your LP lights into that arrangement. Its lock-out function prevents the high and low circuits from being powered together, so you can use the controls you prefer with the correct separation for the lights.

SKU: 640167

Match it to your LP lights and control system

The 640167 harness is for the compatible LP9/LP6 Pro and Racer wiring layout. Use it with an appropriately rated upfitter or power-module installation and follow the light-specific diagram. A separate switch is not included.

The installation uses a 10A-capable low-beam feed and a high-beam trigger drawing less than 1A, as specified in the guide. Check the output ratings and functions on your chosen controller instead of treating every control wire as the same electrical load.

Plan the whole connection

The harness includes the lock-out/relay wiring, battery connections and light leads. Fitting involves routing those leads, mounting the relays and making the specified upfitter and backlight connections; it is a wiring integration job rather than a vehicle-specific plug adapter.

Use it with our LP6 Pro or LP9 Pro lights where the exact wiring applies. If you want an included high/off/low switch instead of using existing controls, choose the 640172 switched harness. The 640168 pigtail is a separate component for custom wiring and is sold one per light.

Frequently asked questions

Why is a lock-out function needed?

LP6/LP9 Pro high and low circuits must not be powered simultaneously. The harness prevents that overlap when correctly integrated with the chosen controls.

Does it include a dashboard switch?

No. It is intended to work with suitable existing upfitter switches or a power module.

Are both control feeds low-current triggers?

No. The guide requires a 10A-capable low-beam feed, while the high-beam trigger draws less than 1A. Match each output to its actual role.

Is it for the LP4 pair?

This harness is for the compatible LP6/LP9 high/low wiring layout. The LP4 has a different function/pin arrangement and its pair includes a harness.

What if I want a supplied high/low toggle?

The 640172 switched harness is the alternative for up to two compatible LP6/LP9 Pro lights. Choose around your intended control system.
