Question:
Hello. Looking to replace my cargo heat 3000. It has a red, black and white wire coming out of the back of it. Do you know what I would do with existing white wire? this replacement heater only has a red and black it looks like. Thank you.

Hey Scott, I looked up your Cargo Heat 3000RV and the company is out of business so there aren't any resources available I can find to determine the wiring color functions of your heater. The heater part # RA3501 does only use two wires (a power and a ground) so is there any way you can trace the wires of the heater you have now and see where they run to determine the functions of everything? Most likely there's a ground and two power sources. Like one that runs from the panel and the other from the battery?

Hey Scott, were you able to trace the wires on your old Cargo Heat 3000 to see how they connect to the new heater? Knowing what you found could really help others trying to match wiring on similar replacements.
