This is a fully plug n play add-on to the 3rd Gen Tacoma rock light harness that allows for independent control of your rock lights. When the lights are activated via CH4x4 style switch the cab lights will not turn on.

The relay module included converts the positive trigger from the switch to a negative to trigger the relay.

The green plug on this harness connects directly to the CH4x4 switch. Making it fully plug n play!
