A-Pillar (Ditch Light) Harness 

Already cut to length, just plug in a pair of lights your vehicle vehicles cowl area. This harness will run from 2 lights to the fire wall of any truck. The Harness is 16awg wire and can support up to 10 amps total in general on the circuit. If you are not putting this onto a fuse protected circuit capable of the amps up to the 10 max that you want to use, we recommend that you add the relay adapter.
This is a direct component harness to connect a single light to ANY Ford Raptor, or Ford Superduty, Bronco, ETC with built in switches. (if you are drawing more than 10 amps though, you WILL need the relay adapter!)
Any other vehicle (Or higher amp switch requirements), with the use of our add on relay/fuse adaptors*
(See detailed instructions for various applications and see below)

You can also add a splitter if you want to connect multiple lights UP TO the recommended amp draw.

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. 

See other optional components to BUILD YOUR LIGHTING SYSTEM!!


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.

Easy and Clean.

Really nicely developed wiring harness for A-Pillar lights. Fit my 2020 Ford Raptor perfect. Finding a way to contain the little bit of extra wire was the most challenging part of the install but better to have a little extra length than not enough. Made wiring the lights a much more enjoyable experience for someone who is not a fan of automotive wiring. Connectors were easy to attach to my trucks upfitter switch wires and it’s nice that they are waterproof connections and will be easy to remove if I ever need to change my lighting setup. Thanks SPV!

Easiest Install

First off, SPV customer service is the best I’ve ever encountered. Second, their plug and play harnesses make installing lights so easy, a beginner can do it. I’m the beginner. I purchased their heavy duty A Pillar Mounts as well. Those mounts coupled with their wiring harness and the marker light harness took all in all, an hour install. Like I said, I’m the beginner, never done anything like this before. Step by step instructions through the SPV YouTube channel made it even simpler. I will be a lifelong customer.

Only way to go!

Sidney was amazing! I had a couple questions about which additional adapters I needed. She totally took over and sent me an invoice with what I needed. Great product from a great company. Will definitely purchase from in the future.
