How to Wire LED Lights to Jeep Rubicon Factory Aux Switches

Many Jeep Rubicon owners overlook the built-in auxiliary switches—and that’s a missed opportunity. These switches come pre-wired from the factory, allowing you to connect aftermarket lights, compressors, or other gear without cutting the dash or adding extra panels. If you’re still running a separate switch setup, it’s time to simplify your install.

This guide walks you through how to wire 3 Inch Led Ditch Light to your Jeep's aux switches and why amber lens lights offer a major visibility advantage.

Step-by-Step Wiring Guide

1. Locate the Factory Aux Wiring

Open your Rubicon’s hood and head to the driver’s side near the battery. You’ll find a small wire bundle tucked away and wrapped in black tape. This is the factory aux switch output. Carefully remove some tape to reveal the pre-labeled wires.

2. Understand the Wire Colors

Jeep color-coded each wire based on amperage and switch assignment:

White (thick) – 40A – Aux 1

Green (thick) – 40A – Aux 2

Orange – 15A – Aux 3

Blue/Pink – 15A – Aux 4

We selected the orange wire (15A, Aux 3) for our amber LED pods, which draw low current and don’t require a heavy-duty circuit.

3. Wire the Lights

• Connect the positive wire from your  ditch light to the orange aux wire.

• Ground the negative wire to a chassis ground point.

• Use heat shrink connectors or waterproof crimps for durability.

• Always test the switch before mounting everything in place.

💡 Tip: If you don't have the factory aux switch package, Jiuguang’s harness still allows full functionality—no cutting or guessing required.

Why Choose Amber LED Ditch Lights?

We upgraded a 2024 Jeep Rubicon with  amber lens ditch lights, and the improvement was immediate. While stock headlights are fine, amber light offers real advantages off-road:

1.Cuts through fog, rain, and snow more effectively than white light

2.Reduces glare and driver fatigue on long trail runs

3.Provides better contrast and road definition in low-visibility situations

Beyond performance, ditch lights feature:

1.Durable waterproof connectors

2.Glossy black housings that match the Rubicon aesthetic

3.Compact size for a clean mount on bumpers or roof racks

No Aux Switch? No Problem.

If your Jeep doesn’t come with the factory auxiliary switches, you’re still covered. Jiuguang lighting includes a complete plug-and-play harness with their lights. You can connect directly to your battery and use the included switch—all without drilling or complex wiring.

This makes ditch light lights a great option not only for Rubicon owners but also for other Jeep trims, older models, or even other off-road vehicles.

Final Thoughts: Clean Installs Start with Smart Gear

Jeep built the aux switch system to make life easier. When paired with smart gear like Jiuguang’s amber LEDs, you get a powerful lighting upgrade with minimal wiring hassle. No dash mods. No aftermarket clutter. Just crisp visibility and a system that works the way it should.

Don’t let those switches sit idle. Whether you’re gearing up for snow runs, desert trails, or backwoods overlanding—give your Jeep the lighting it deserves.
