Thats interesting I don't think I have that system if I do I've never seen it. Odd that its controlled through that electrical distribution panel and not the engine panel in the back.

Thanks Carl. Newell discontinued that system somewhere between 96 and 99. If you look on the back of the temp control for the dash heat you will find a microswitch. I can tell you that the dash heat works great with that booster pump, and is worthless without it. So worthless, that Newell started installing separate heater cubes up front using the Aquahot system.

Hmm I wonder if the micro switch is bad on mine. No matter how I wire the relay, the pump in the back runs nonstop. For now I've got the wire unplugged.
