My Captain Fantastic has what appears to be an EOS switch on the 00-90 stepper unit that must be there to help keep the coil from getting fried. It's mounted to the coil bracket through the two little screw holes as shown in the pics on post #4 in this thread. It's connected by a gray/black wire and a daisy-chained yellow wire. It has a white plastic vertical switch actuator that opens and closes the switch.

My question is: should the longer leaf of this switch be located in the slot of the actuator or outside it toward the coil side?

Thanks.

Quoted from xsvtoys:

Given the wire colors you describe and looking at Capt Fantastic schematic, I am pretty sure that switch is connected to the alternator relay. The alternator relay in turn controls the lighting and scoring on the 3 pop bumpers.

Yes, that is correct.

Here is my switch:
