I just purchased a 2002 Grizzly 660. I THINK it is the Hunter model because it has a factory winch and the full LCD instrument panel. It is early enough that has the 5 MPH limiter when in front wheel locked operation. It is green if that matters. The manual I got has wiring diagrams for the 660FS and 660FP. How do I know which applies to my machine? What is the difference?
