Adapter after basic connections.
So, after making the basic connections, you should have an adapter that looks something like this. Pic on left is parts (comp) side and Pic on right is solder side.
Now we have the controls and speaker connections to make, these will invovle the second small 2 x 10 way edge connector, the track ball and the amplifier for the sound.
At this point, i get a paint pen and write on the edge con what game it is for and i also write parts on the part side and solder on the solder side.
This way at a glance you know what its for and which way to put in on the pcb.

Small edge connector.
The small edge connection on the Crystal Castles pcb is a 2 x 12 way, but these i could not find anywhere, so i got a
2 x 10 way one instead and modified it to fit, as luckily, we dont use all the pins on the small connector. I used a 1mm thick needle file and a disposable stanely knife, to create a slot in the end of the edge connector. I started by filing first (pic on left) untill i got down to a point where i would of started to rub against the pins inside. Once i got to this point i used the knife to cut little nicks out, untill i was flush with the bottom of the ledge (pic on right).

Small edge connector cont...
Once i had done this i gave the whole connector a good blow out with an air duster (can of compressed air). Then i lined the edge connector up with pin N on the edge connection (1st pin on left, see pic on right) so that pin A and B hung out of the right hand end of the connector through the slot i had filed / cut earlier, it was then a matter of pushing it on, so that it sat in place.
Now is a good time to get a paint pen and right part side on this con too.

Small edge connector wiring.
Now we need to make the connections for the trackball, so i cut a 12" length of black wire and red wire and 2 x 12" lengths of blue wire and yellow wire, so you should now have 6 x 12" lengths of wire. These i then stripped 4mm off of the sheathing, then twisted the exposed wire and then tipped these will a small amount of solder.
You need to solder these wires to these pins on the edge connector :
Black (Ground) to pin N (parts side)
Red (5v+) to pin M (parts side)
1st Yellow (Horizontal Dir) to pin E (parts side)
2nd Yellow
(Vertical Dir) to pin F (parts side)
1st Blue (Horizontal Clk) to pin 5 (solder side)
2nd Blue (Vertical Clk) to pin 6 (solder side)
I then cut 6 x 10mm lengths of heat shrink and slid these over each wire and right up over each pin and then shrunk them on using a cigarette lighter. This then avoids any close pins touching each other.

Optical wheels and loom connectors.
Turning the enclosure on its side (so that the right encoding wheel is facing you) you will clearly see the wheel with its windows, in front of this, is a molex type connector which has 4 pins, with the trackball in this position, i number these pins from left to right : 1, 2, 3, 4 . So this is the Right hand connector and the wiring for this is as follows :
Pin 1 = Horizontal CLK
Pin 2 =5V+
Pin 3 =GND
Pin 4 = Horizontal DIR

Now turning the enclosure on its other side (so the left encoding wheel is facing you) i again number these pins from left to right : 1, 2, 3, 4 . So this is the Left hand connector and the wiring for this is as follows :
Pin 1 = Vertical CLK
Pin 2 =5V+
Pin 3 =GND
Pin 4 = Vertical DIR
