blitz boost controller wiring

[Noventa]

hey guys, I just bought a blitz dsbc off ebay and am currently trying to wire it up. Looking at it, I notice that there are 3 set of wires coming from the actual controller. Obviously, the 4 prong one seems to connect to a harness that leads to that big "black box". (the one with "in" and "out" labelled on it) My question is, can anyone tell me what the other 2 sets of wires coming from the boost controller is. One is a 3 prong white clip, and the other appears to be a semi-rigid black tube.

thanks in advance
