If you look at this pic;
Near the dipstick you can see the rubber hose and where it joins to the vacuum pipe going to the servo, look for a small while adaptor.
Brown wire goes to ignition switched power source, you can take this from the fuse box
Grey wire goes to the VSS, you can take this from behind the instrument cluster, from pin 18
Red wire goes to the live side of the brake pedal switch
Purple wire goes to the other side of the brake pedal switch, to cancel the cruise control if you touch the brake
Blue wire goes to the rev counter, you can take this from behind the instrument cluster, I think pin 21
Black is earth, ground to one of the mounting bolts
Green and yellow go to the control
