I want to be able to just make the momentary switch active or deactive.

Because you are interrupting the signal directly with the momentary switch, it will be difficult to also add a toggle switch. The only method I can think of is to add a relay.
Use a relay to interrupt your crankcase signal. The toggle switch and momentary switch in series would be used to apply power to the control (coil) side of the relay. You could do the same thing with a FET or transistor but a relay is probably simpler.
