Hi Dan
this needs checking but could help
GX12 - 3 or GX12-4 chassis plugs will fit into the holes in the box for the limit swich connections
one thing I would change is the GX16-5 chassis plug used for the spindle motor
this 4 pole touchproof socket is a possible solution

the wire colours are likely to depend on who made your control box and what was the cheapest cable at the time

to connect to the breakout boord inputs I think you need a
Hilitchi 2.54mm JST-XHP 5 Pin Female Pin Head Connector
ebay & amazon sell a kit of 2 to 5 pole plugs and sockets
