The 36 pin connector is ground wired to 1-4, and A-D.  Then wire +5V to 15-18, and S-V.

The power harness is as follows:

1       Ground
2       Ground
3       Ground
4       Ground
5       +5VDC
6       +5VDC
7       +5VDC
8       -5VDC
9       +12VDC
10      key
11      +12VDC
12      +12VDC


To use the board without a coin meter, you must insert a jumper across the points of J7
(located near IC 60, the large brown SIP IC near the G connector).
