I am having trouble now thats its gettin coolder here in Indiana. My grid heater started cycling while the engine was at operating temp.The outside temp was 57*. What a battery drain that is. Is the sensor on top of the intake towards the back, the one that controls them. 1996 3500

 

Yep, that's the location

 

Thanks for the schematic Fueling Around

 

One of the many things available from www.dodgeram.org

 

Took it out and cleaned it with contact cleaner wiped it off works like new
