Williams EM cable colours

[RichS]

Ladies and Gentlemen

I am currently working on a 1955 Williams Smoke Signal pin. I have the schematic but whilst is shows the cable colour numbers, there is is no cable key on the schematic. Do all early Williams Games have the same colour code? Any advice much appreciated

All cable colours will differ per machine model. Black cables will carry power from one side of the transformer and the other, perhaps yellow, will be on the other side with all the various relays, etc in the middle, identified by said colours. Put a few pictures of the schematic up and I should be able to tell more.
