I have an 07 Rhino 660. After sitting all night, turn ign on, temp light is off, start cranking temp light comes on, engine starts temp light goes off. Shift to HI and temp light comes on. Coolant level is good , level in overflo tank is proper. I've been trying to trouble shoot wiring, but only have the diagram for an '06. The wiring doesn't seem to match, is the '06 dash wiring the same as '07? Where can I get the wiring diagram for the '07. Thanks for any help or guidance you can give.
