Answer CP, There should be two(2) terminals on the new switch, and wiring is not polarity sensitive, so location of the wires is pretty basic.

The other terminal will have three(3) wires attached to it, the two blue wires, that are routed to the receptacle in the cooking bays, and the thinner black wire that is routed down to the vent motor harness.
