I have been researching a way to hook up a second sending unit in the hot water line going to the hot water heater. I want to be able to read coolant temp on my Vulcan 7 through my NMEA 2000 network. So I need the sending unit hooked up and I need a device to wire the sending unit to that plugs into the network! I have found a similar device to feed fuel levels to the Vulcan but can’t find anything for coolant temp! Everything I have found on the forum is fairly dated. Any advice with this upgrade??
