On the matek receivers, what would normally be in the signal position (white) on pin set 7 is the sense pin. (I soldered a red pin into that position on mine)
For total pack voltage sensing, that should be connected to the red wire on the balance plug.
The red and black of pin set 7 on the matek receiver do not need to be connected to anything.
On your balance connector, the black is ground, the red is total pack voltage. The other 2 tap into the connection between each cell in the pack.
You could monitor just the voltage of the lowest cell by using the first wire next to the black, or the total pack voltage by using the red.
