Well, this was a mess, and I blame it on myself. In my rush to work on the box, I disconnected all the plugs, I just wanted them out of my way. No, I did not cut them nor did I record what was hooked to what and where.  So I had to do this one on my own.

On the back of the unit, there are five 50-pin male receptacles, which are 10 x 10 easy. The Jacks are labeled J1 through J5 and have cables attached to them. The other end of the cables has a 34-pin male header. One is pin 1 to pin 34, while the Other is pin 35 to pin 68. Onto these headers, you have female headers of assorted sizes. Below is two tables that show the interconnections. The first table is to show the interconnections between the Jacks on the rear to there destination (From - To). The second table is pretty much bare as I have started to figure out the interconnections between the displays and the Jack field.

The plan is to build a backboard with 5 headers on it, with two Arduinos Megas there will be an ethernet shield to send data to the NavIOSS (IOSS I/O Subsystem. I will use I2C to send information between them.
