I've been getting back into arcade gaming lately. I'm up to three cabinets and counting, all Sega, and all using the same AMP/TE Universal Power connectors for basically every internal interface.
So I scoured the internet for the pinouts, and whipped up a wiki page with all of it:

Corrections and suggestions are welcomed.
super clean pinouts, with ultra clear images. Wish other websites did it this pro!
