Many thanks for all the superb comments guys.
Made up a little loom for the fuel pump relay tonight. Still requires the trigger wire but this can be done on the day. You'll notice the small red Deans plug with fly leads to the pump. This is so I can just unplug the pump and with just one bolt and 2 fuel fittings the whole pump/filter cradle can be removed to get super easy access for changing spark plugs.
