Help wiring 8s Lipo to BMS

Hello all, I’v purchased a Zippy 8s 5,800mAh Lipo from Hobbyking,, and this BMS,, but can’t figure out how to wire the balance wires together. The battery comes with 2(4s) plugs for a total of 10 pins, while the BMS has 9 pins but 8 are used in the schematic,

Do I get rid of the red wire in the middle, connect the first red to the charge port and connect the negatives to the BMS, or connect the middle + and - together while connecting everything else in order?

Cheers, Malik R.
