Also wondering if any of these would cause my symptoms:
1) engine coolant temp sensor
2) air conditioner switch / engine coolant temp switch?

I am assuming this is the engine coolant temp switch? It is forward of the thermostat housing, right above the engine coolant temp sensor.




The Raider Service Manual electrical diagram only shows a single Black/Yellow wire to the switch, but there is another green/red wire that is not in the diagram and looks to be wired incorrectly. The switch has three terminals for NO (normally open), NC (normally closed), and (closed). Which wire should be where?

Not sure if this is related, but my AC stopped working during a long trip from SF to LA a few months ago, when the high/low idle problem started.
