Sens-a-brake Evo wiring

Hi fellow Bogers, I'm installing a Sensabrake EVO but the wire crimp pins on the 6pin plug that connects to the under dash control unit have dislodged from the plug and the manual that comes with the unit doesn't cover this plugs pin-out There's a orange,brown,yellow &blue wire but the blue is the one I really need help with. The power connect plug is fine but any help with this control plug will be really appreciated, Thanks-Graham
