Skee Ball Alley - Help reconnecting wiring harness

[vestaviascott]

I recently purchased a classic 13 foot skee ball alley made by Skee Ball, Inc in 1988. The wiring was disconnected for transport and I wasn't able to get a shot of the connections prior to them being disconnected (previous owner dismantled the machine himself in prep for my pickup).

Any help or insights would be much appreciated. Best I can tell, this is a Model "S". The manual along with wiring diagrams are contained.

Here are the two wiring harnesses coming off the left side of the cabinet. They actually match up pretty well with two of the connectors on under the ramp on this same side:

What I'm not certain about, in the pic above, you can see (1) a yellow wire that has no connection and (2) there is a pigtail you can see that's inserted between the two connectors. This pigtail appears to serve one purpose as you can see a single red wire coming off the pigtail and going to the other side (right side) of the alley.

Here's a shot of the connection on the right side where you can see that red lead wire that's coming off the pigtail from the left side in pic 2 above:

Plug it in, turn it on, what happens?
