Which of the RJ12 wires supply power to the BMV 702?

My BMV 702 has stopped working (blank screen). I have confirmed there is power at the shunt and now want to check if there is power at the monitor end of the RJ12 cable. Can anyone tell me which of the wires/pins in the RJ12 cable supply the power?

Thanks @Farriaza.

But is that from above, with the pins facing up and the connector facing away from me?
