Pinscore power supply yellow 2wire connector on Black Knight?

Hey guys,

Just installed this in my system 7 Black Knight. There's a yellow 2 wire connector hanging from the board that didn't have an equivalent on my original Williams power supply. Does this need to connect somewhere or is it for a different Williams game?

Did yours originally have a system 6 style power supply, with the big transformer in the backbox?

Yep, that's a system 6 style power supply in that one, early production machine.
The power supply you got is the later System 7 style, which for the most part is far superior.

The difference is that System 7 style power supplies had the relay for the GI lighting mounted on the board. System 6 style machines had it wired externally, it's that little box to the left of the power supply transformer. So, in your case, that extra connector on the new power supply isn't needed at all.
