I have a BMV-702 in our 5th wheel right now and recently purchased a BMV-712. I want to put the 712 in our 5th wheel and the 702 in our travel trailer.
Do I need to replace the 702 shunt with the 712 shunt in the 5th wheel or are they interchangeable and I can just replace the meter? I'm not sure if the circuitry is the same on both shunts.
