As I was busy Richard sorted the wiring out for the control box:
Wiring, inside the tub running along the tank with the rest of the rear loom
Wiring running along transmission tunnel, protected by a piece of fuel tubing to stop stray debris from damaging it.
Behind the fuse box, hooked in via 7.5amp fuse to an ignition feed
Located the control box in the same area just off the centre console.
Everything back in place under the dash
Just needs the rear putting back together again.
