In my original Playboy schematic, it says N/U next to the 13th wire. So I'm guessing Playboy didn't need it.

The molex plug is supposed to have a little key in the eighth hole so that it can only be put in one way. The key in the plug must align with the missing spot on the rectifier board.

OK. Deep breath. In... Out... In... Out... If your GI lights are coming on, that means your outlet, filter and transformer are all fine which means you have power to your rectifier board. The next step is to see if you have power where you need it on the board. Disconnect J1 and J3 from the rectifier leaving only J2 plugged in. Turn the machine on and read the test points. I'm assuming at this point that you have a multi-meter and know how to use it. If you don't know how to read it I can help. If you don't have a meter you should get one. 40 year old pinball machines, while reasonably reliable, will get cranky at some point.

In the third picture it looks like he did fix the GI on the J1 plug. So if all the green lights come on I would assume that means your voltages are within the needed parameters. The next step is to plug in the solenoid board and check the voltages there. Here's the relevant test points.
