Looking at the paytray from the side of the hopper, there are 2 connectors, the one on the left is black with orange/black wire. The one on the right of the hopper is white with orange/blue wire. Looking from the far end which has a connector block on the right which when pushed in goes into the back of the cabinet.
In the middle there is another board with 3 connector blocks pushed into, then looking back into the casing there is 2 connector blocks not connected into anything one has six wires, the other has 2 wires, they are both white connector blocks.
Hi Baz
The only one on the board I can find is payout which is connected, where the coins go in there is a big clump of green wires which are connected (towards the front) an on the left hand side there is more wires with conector (about 6) which is connected, mainley green, also 1 more connector block (red wire). This looks that it is just connecting a couple of the terminals toghether. There is also a loose connector block with pinkish wire on, simular to the red one which is just hanging.
The hopper is called compact hopper, with a coin controlls sticker on it and has a rocker switch by the front. Cheers
