Hi thanks to Rusty for the diagrams, a lot to download but it seems that my assumptions were correct, the unit needs a 12v feed and an earth connection, the 3rd wire is a trigger to make the pump work, so I've wired this to a brake light switch so the pump operates when pedal depressed.
Oh it's not being fitted on a J in case you wondered, it's going on an old car without servo brakes, the J vac pump was the cheapest way to get vacuum for the retro fit servo without tapping into the manifold.
