Wms bb1 cat 5 cables and errors

[Nepa Coin Op]

I’m working on a bb1 here that I messed with years ago and don’t remember but may have borrowed a cat 5 or 2 from. I’m finally putting this machine back together a customer wants it as soon as I can get it done. I’m unsure if im missing a cat 5 or not somewhere.cat port to the far right on the reel controller board is open as well as 1 and 3 on the credit display….. when this game is booting the the reels are not spinning during boot , power supply is brand new and all voltages present. Current errors after boot are

Single row animator
Lamp matrix
Payline 20 display
Led display

All command time out…

I’m pretty sure I’m missing something stupid from when this was apart but just don’t remember where. These have a lot of unused plugs and so I so I don’t want to just plug stuff in without confirmation.

Any guidance and help is greatly appreciated

Thank you !!!!
