I had two BMV-702 installed in my boat last year and when examining the shunts I notice they are slightly different. When looking at the shunts from the top, one shunt has the RJ12 connection on the right and the other shunt has the RJ12 on the left. The online installation guide shows the shunt with the RJ12 on the left ( figure #6). I am wondering if this is just an older version of the shunt where the connections are reversed. I want to make sure the load/battery got connected on the correct sizes. Cheers
