In my au 2 ute there is a blank cover to the right of the steering collum on the dash. behind it theres 2 spereate connectors/plugs one black and ones grey. one when bridged out seems to controll some sort of realay under the dash. anyone know what they are for? thanks

That part of the dash is for switches to go in. Same as a sedan, they are for Boot open switch and Fuel Flap switch. They just have a bezel to cover the hole and the Harness is the same a a sedan too, hence the reason for the wiring plugs.
