Super Stuff Daniel !
"M" Relay is the 100 Score relay. It has 5 pairs of switches. All are normally OPEN, Except a set of contacts with a Maroon/White wire and a Maroon wire. This set is normally closed.
These three contacts in a stack of THREE were OPEN
Top set was closed and bottom set are open on this side
Sorry if the pictures are crap - the flash blurred them
