RCATs should be able to tell you, but I imagine you hook the switch in series between the primary side of your magneto coil and ground. Then the switch connector is plugged into an auxiliary port on your receiver. RCIgn responded up this thread a ways about a black wire. I don't have a G26 but there's got to be a ground wire somewhere on the engine. Look in the manual and see how they recommend hooking up a manual switch. It'd be the same, except you use your electronic switch.
