Wire up your own switches with the Trail Rocker Relay Center from Painless, allowing you to control up to eight accessories on your TJ Jeep! This kit uses the same relay center found in our other Trail Rocker systems. However, it comes without the switch panel allowing you to wire up your own switches. The heart of this kit is enclosed in the weatherproof housing that surrounds the relay center with eight fuses and relays. This kit provides you with all the necessary weatherproof connectors and wiring to connect to your Jeep accessories ranging from lights to air lockers. Easily installed with our detailed instructions and plug-n-play design. Winch Ready! The Trail Rocker system includes dedicated wires for controlling a Winch. Purchase of our Winch Control Add-on Kit part number 57150 is required for operation.
