Overview
The Jeep OEM Wiring Harness 56055357AF is the factory chassis wiring harness from the Rubicon model. It is meant to make upgrades easier on a non Rubicon Jeep, including Rubicon Dana 44 axles, sway bar disconnects and factory fog lamps. It plugs into a non Rubicon model, but some wiring is needed to make everything fully functional with the Rubicon axles.
Key features
- Factory chassis wiring harness from the Rubicon model
- Plugs into a non Rubicon model
- Supports upgrades to Rubicon Dana 44 axles
- Supports sway bar disconnects and factory fog lamps
Planning a wiring upgrade
Adding a factory-style harness changes how several circuits share power and ground. Before connecting anything, map which circuits your current vehicle already uses and which ones the new harness will feed, so no circuit is doubled or left without a fuse.
Wiring upgrades rarely stop at the harness. Axle and accessory swaps often need new relays, switches and grounds, and connectors should be checked for corrosion before mating. Test each circuit with the key off, then with the engine running, and label any new wire runs for future service. Keep the harness away from sharp edges and secure it with factory-style clips.
- Check existing fuses and relays for the new loads
- Clean ground points before bolting them down
- Use dielectric grease on sealed connectors
- Route new wire away from hot and moving parts
