@nuttygt4 sounds like you are going off on a bit of a tangent here to the original purpose of the thread ?
If i understand it correctly you have the engine heater and want to change it over to be a parking heater and feed the cab, to my knowledge regardless of the overhead unit you need to flash the firmware of the heater to make it compatible with this function and accept external inputs to control it ?
I think a couple of the guys that have done this may be able to provide some info and then maybe we can split this into a separate thread
