I am going through a Captain Fantastic after swapping the playfield and I have a bit of a mystery to solve.
One of my first steps is to check that all switches that fire the score motor are working. I've checked each except the switch on the 10-12 Play Relay. I can't find this relay. On the schematic this relay is connected with a dotted line. Does that mean optional? I've gone to the switch that is supposed to fire the 10-12 Play Relay, which is on the 3rd Coin Chute Relay. The switch with the yellow wire on one side and Grey Black on the other should fire the 10-12 Play Relay. The switch and wires are there, but closing the switch does not seem to do anything, so I can't find the missing relay.

Does anybody know where it is and what it does?
