There's a single ribbon cable that runs from the gripper end all the way to the logic board. It has 13 wires. One edge is painted black - that's the index for wire 1.

There are 9 limit switches along the length of the run. These are divided into 3 groups. Each group shares a common ground signal.

Here's the wire definition for the 13 signals on the ribbon cable, grouped.

1 Ground
2 Cube touch DIO-0
3 Wrist down reverse
4 Wrist up forward
5 Gripper closed reverse
6 Gripper open forward
7 Climber DIO-4

8 Ground
9 extension limit far reverse
10 extension limit near forward

11 Ground
12 arm rotation limit up reverse
13 arm rotation limit down forward

3, 4 Gripper closed reverse
5, 6 Gripper open forward
7, 8 Wrist down reverse
9, 10  Wrist up forward
11, 12 Climber DIO-4

(cable with black index)

I messed up while attaching the cable to the limit switches.
