The top of the weatherproof fuse & relay center features the stylish logo silkscreened onto it. Along with the fused power source mounted next to it. Underneath the fuse & relay center you will find the powder coated custom mounting bracket with stainless hardware. This bracket is designed to install in existing mounting holes under the hood. 


The heart of the Trail Rocker is the fuse & relay center. Here you will find eight 30 amp fuses and eight 30 amp relays. 


The 200 Amp MIDI fuse comes pre-installed ready to protect your investment! 

The underside of the fuse & relay cover has a built in gasket to help keep any moisture out and to act as an extra support for the relays. This extra support on the relays ensures that no matter how good or bad you are on the trails, the relays will not pop out of place. 

Attention to detail shows in this bolt with O-ring combo to hold the top cover on.  




This harness attaches the fuse & relay center to the switch panel. It’s a plug-n-play design that only requires you to route it and plug it in.  


Mounted inside a sealed switch panel, these switches are vibration, shock, thermoshock, moisture, and salt spray resistant. 


Exiting the fuse & relay center we provide you with 21’ of wire to reach any 12 volt accessory you have.

Printed every 12” on the wire you’ll find the circuit description, a signature touch of ours. 

The parts kit comes with everything you’ll need to install the Trail Rocker, except the tools and the Jeep.

You’ll also find a custom pigtail that allows the Trail Rocker to power up only when the key is turned on. The system is shipped to be powered at all times. 

You'll also find a winch pigtail that is pre wired into the kit. This pigtrail is ready to wire up to your winch. The other end is ran up to the switch panel. With the purchase of our custom winch switch PN 57150. You can easily replace one of your switches and control your winch from in the cab. Be sure to visit our wiring schematics page for details on wiring this to your winch.
