I've just found some pinouts I documented years ago for the SSL 6 way console Bicc pinouts as plugged into the upper buscard (see attachment).
These show the channel functions and the main power Bicc, B3. I think the only change may be the track remotes (from DL's 41 and 42 etc) which were rewired in the 1980's so I'll post more info on that later to update this post.
By the way, I have lots of these 6 way Bicc connectors available along with the various female and male crimps in different sizes to suit the different Bicc looms that SSL made (in rectangular or circular form) including the larger size power cables that used up to 25/0.25 gauge wire.
Hope this helps and is accurate. Regards from Jim Lassen (
