Pinout for BMV700 RJ12 UTP

Hi,

I am looking for the pinout of the RJ12 UTP cable used between the shunt and the BMV700 display. My display has quit and I want to make sure the cable is good, and that it is getting the right bits from the shunt. I have been unable to find a replacement shunt board in the US and I don't want to have to just buy a new BMV.

It's pin-to-pin. Eg Pin 1 to Pin 1, Pin 2 to Pin 2, etc.

So a simple straight through cable. What are the pin functions? I assume there is a +12v and -12V pin and some data...

I don't know what the pin functions are.
There will be BAT- , CHARGE/LOAD- , B1+ , B2+ (MIDPOINT / TEMP)
Maybe BAT- and B+ are over two conductors, but I don't know, I have not investigated this far.
