hey guys,

can anyone point me in the right direction in terms of electrically wiring this board?

https://docs.google.com/document/d/1VMO3VfIBy3KIwUaaQ8XhKrSVEbXeeMEqsVhhk6Bz9io/edit?pli=1

so the doc says this:

1. The two poles for the positive polarity are identical when cabling from the PSU, so are those for the negative polarity.

i'll be getting myself a psu with 12v/10a output so when i bare the wires, how will i know which wire goes into which hole? the picture below belongs to LainZ and i'm trying to figure out how to wire the board when it arrives...
