The harness is generic, intended to fit multiple models and is not fully customized for any particular make or model. Some adaptation may be required for your particular application. The kit includes a switch box, 4 toggle switches, a fuse block with 4 fuses and wire harnesses to power the front and rear work lights, a dome light, the heater, a circulation fan and a beacon light (these optional accessories are all available at extra cost). The heater switch is a 3 position switch, while the remaining switches are 2 position switches.
