I dont really know much about them to be honest but behind the EBC - 3 cables , 1 for power with socket/plug ends up in the black box in the engine bay (top left of pic). The second one is unused and seen hanging in the pic and the third one runs into the engine bay marked 1 on the pic and finishes up with a T-joint (in pic)

is the harness to the black box in the engine bay connected up? you said that there's three cables coming out the back, one should be for power (going to your fuse box) with a black ground wire going to the chassis, then there should be a harness going to the black box, that should go through the firewall into the engine bay, then there should be a black hose(not a wire) going to the intake manifold. All these should be connected for it to work, i cant see how why there should be one hanging down un-connected.
