Does anybody know the purpose of these wires on my controller?

Bought a new controller recently, it connects to the bike - power comes on, however I need to purchase a PAS to see whether the bike will work. So far, I'm pretty confident it will because the battery comes on & the motor connects. My old PAS is not compatible with this controller (I was aware of this prior to buying).

I was under the assumption that the yellow 3 pin wire on the controller would be for the PAS? But Now I'm not too sure with the other two wires I have discovered on the controller. Before buying this one, the picture in the advertisement did not include the three additional wirings.

Any help is appreciated :)

Please see 'Screenshot_3' (All 3 of the wires pictured) to see which I am on about.
