I recently bought a TAF that was not working but the boards were there. It has a A-12697-3 board that is missing the connector and relay among other parts. The wiring harness has a connector that I can't plug in, looks like flipper control. I have flippers but they're weak. I swapped with a -1 board and it works fine. Can anyone tell me which specific games use the -3 and and is there a kit or parts list available to upgrade?
