Already cut to length, just plug in a pair of lights in the REAR of your vehicle. This harness will run from the rear ALL the way to the front engine bay of any truck.
This is a direct component harness to connect a pair of rear lights to ANY Ford Raptor, or Ford Superduty, Bronco, ETC with built in switches.
Any other vehicle, with the use of our add on relay/fuse adaptors*
(See detailed instructions for various applications and see below)

Our new REAR harnesses have 2 access ports for use with our optional tail light adapters. If you would like to trigger your rear lights when you put your vehicle in REVERSE as WELL AS on a switch... Be sure to add our Tail Light component that matches your vehicles tail light. These will power BOTH the reverse trigger of your lights, as well as the red backlight from the marker/tail lights if you have a light with a secondary backlight. 

UPDATED 3/1/24 -

We have upgraded our full rear harness to 14awg wire (Previously 16awg) to handle the heavier lights and bars people are using. We also extended the ground connection all the way to the front with the other connections. This way the harness can also be used for things like Chase Light Bars or on on top of truck beds where finding a ground bolt can be difficult.

Harness System Description-

This harness is part of our UNIVERSAL harness system. Each harness can be used for virtually ANY vehicle and ANY lighting application with the use of our many adapters and modules. Each adapter or module will simply plug into the harness to fit virtually ANY light.
For example, if you have any light such as Rigid Radiance, Scene, 360, or any other make and model WITHOUT connectors on the bare wires with the lights. You will simply add on the included matching connectors in the included kit. 
If you have lights WITH connectors on them, you just add the correct connector adaptor type. Some examples of connector adapters are- Rigid Pro Series lights or Single stage lights use DT connectors. Baja Designs (For the most part) use WP Connectors. If you have a 3 wire light (With the Amber/Multicolor background) you can use the included plug pack to either add to your lights 90% of the time, or your light will most likely already have the 3 way WP connectors on them, which will match to these harnesses. 

These harnesses also can be interconnected to other adapters from the system. Including Tail Light or Marker Light Trigger adapters to trigger reverse lights, marker lights to backlit lighting, etc.

This Component is a stand alone harness that is all you will need in applications like the Ford F-150 Raptor, where you are connecting in to the vehicles BUILT IN RELAYS and FUSES. This harness is not FUSED and therefore, if you are connecting it direct to ANYTHING other than a fused circuit, you MUST connect our add on Relay/Fuse adaptor to protect your lights and vehicle from fire. We are NOT responsible for incorrectly installed equipment. If you have questions, please refer to the chart, instructions or reach out to us so we can guide you.
