This information comes from two different schematics. One appears to be a generic schematic for the board set, and the other is a schematic for the Bump and Jump wiring harness. I haven't verified which is really correct, but I would assume the wiring harness schematic is correct for Bump and Jump.

NOTES: A) The generic schematic shows pin F is Coin Switch 2. The Bump and Jump wiring harness schematic shows both coin switches going to pin 6, and "Service SW" on pin F. B) These pins are shown on the generic schematic but not on the Bump and Jump wiring harness schematic. They are apparently used by games other than Bump and Jump.

NOTES: C) The generic schematic says pin C is "TV GND". The Bump and Jump wiring harness schematic shows it going to the -Sense line of the power supply. D) The generic schematic says pin 3 is Ground. The Bump and Jump wiring harness schematic shows it as the shield (gnd) going to the monitor. E) The generic schematic says pin D is "SYNC". It is not shown on the wiring harness schematic. I suspect that pin D is composite sync, and that the game really uses pins 6 and 7 for V and H sync.
