as far as i know its the standard pink coloured relay that goes behind the dash next to the drivers feet, the relay base should be the same pinky/purple colour, its the same relay as fitted to all xr31's and s2 turbos, the only one that was different was the series 1 turbo which had a silver relay and an extra termial on one end, it will run if you make a temporary link from the ignition live supply to the blackand red wire, this will put a permanant supply to the pump all the time that the ignition is switched on
