There are FIVE general illumination strings available in WPC-89. The WPC manuals do NOT adequately document the lamp locations. Sometimes the test (T.6) will indicate which string corresponds to what area but it isn't precise. You will need to scour for images documenting this. Christopher Hutchins (HEP) usually has excellent images for this purpose.
The five strings are:
- BRN / WHT-BRN
- ORG / WHT-ORG
- YEL / WHT-YEL
- GRN / WHT-GRN
- VIO / WHT-VIO
The only dedicated use of any of the strings is VIO / WHT-VIO that taps off J119 to feed the coin door (insert coin lamps).
As previously mentioned the Williams manuals are mostly correct. They aren't always correct so read them and trust them but verify them.
For instance ... take a look at this from The Addams Family manual.

It clearly has errors in it. As general illumination is AC your electrician office workers will probably understand this better than the DC wiring. There is a "hot" wire and a "neutral" wire. For our purpose let's just call the solid wire color hot and the WHT-XXX wire neutral. One side is actually tied to the cabinet ground but I can't remember which it is and I'm not interested in looking it up to be precisely correct.
The wires are paired. One solid color hot and one striped (WHT-XXX) color neutral. They are always paired. The wiring diagram shows a BRN in J121 but no WHT-BRN in J121. That doesn't make any sense because there's no neutral (return). Also ... there's no connection to the GRN / WHT-GRN pair and there's only a single WHT-YEL connection.
Not only is this documentation clearly wrong there is no indication of which strings go where. Again ... you will have to use images scoured from restorations to find this out. Or ask someone who has this information (in images) to post it.
The general illumination is often a single connection to a socket and then wired in parallel to the remainder of the sockets in the string. This parallel wiring is done with the same solid YEL jumper wires Williams used for switch column chaining.
Finally ... when you turn to wiring up the solenoids I STRONGLY advise that you don't try anything (applying power) until you post images of the wiring you have. If you have wired up something incorrectly you WILL damage something with this high voltage. Go slowly here or you will try to take one step forward but end up taking FIVE steps backward.
