its a power connector chris. its disconnected on the one here as well and going on the way its squashed its never been used.

from the manual it seems to be A10P4 "to led display". suggest you deem it unused and move on

looking at manuals like black hole and mgow suggest its used for cabinet lamps this game doesnt have.

Operation Thunder gents. Could you take a pic of the center upkicker wiring on the lugs/solenoid? Just bought mine and lugs with wire were broken off the solenoid. Also, previous owner had "someone" try to fix it before so I am not sure if I have it wired properly. When tested onsite, left and right upkicker were functioning. Replaced solenoid and soldered wires on to what I thought was right but now, all three don't seem to be working. Fuses were checked. Thanks in advance!!!
