you don't have to jump those terminals.
all that is needed is to wire the G terminal to the mounting bolt, completing the ground circuit. [a spade connector, short piece of wire, and a ring connector terminal]
however, doing that allows the car to start in any gear, so BE VERY CAREFUL if you do this !


edit : the above i posted is used to bypass the NSS using the key to start the car. using a bump switch to run the valves requires hooking up the switch as the picture indicates.
sorry if i caused any confusion !
