I installed the system on my rig and from the looks of their schematic I would say NO it will not interface with anything. They basically have a closed system that connects the sensors on a buss and the display will see each sensor on the buss depending on how the sensor is configured.
I have 2 displays plus the optional propane sensor and absolutely love the operation. I could now care less if my internal sensors get crap on them.
