Each module had the same IO arrangement, but the wire colors for the first assembled module were not chosen to be reproducible. For the next four, reproducibility was key, so a cable was salvaged which had the same twisted pair color combinations as standard ethernet cables but had no sheath. Six operators, two of which required two wires each, meant exactly eight conductors.
As the first module was wired, all the bends and lengths were copied to the wires of the same color to ensure that the wiring matched on the remaining modules. This would make testing easier since problems which occurred on every module could be repaired the same way while unique troubles could spot discrepancies to fix things.
Everything was given wires long enough to connect to the junction boards which would be installed as each section was completed. The purpose of wiring in a specific order should have been to start with the devices closest to the controller (e.g., the screens) and get them working before moving to the operators which were further from the controller. This wasn't planned well in advance.
The rest of the posts for this project have been arranged by date.
