Green/red on the inside lug and Yellow/black on the outside lug. It's the same on Wiring to the coin door lights on all 4 of my Bally's.
that's how I wired mine but not lighting. I even reversed just in case and a few other configs with no luck.
Nice soldering btw
Just check you actually have power then. Using the socket you have, put one wire on the central tab, the other on the barrel and the lamp should light (don't have the socket attached to the machine). Alternatively, put your multimeter on AC and check for around 7v.
