(ET) Where is CB-1 on an E12M?

[tb <tbamc gbta net>]

I ask because I sure can’t find it on mine.

Finally found it on a  diagram in the manual, but that shows it at the 
back/top of the traction motor—and I don’t see it there, or see how 
there’s room for it there.

I did find a couple of unconnected wires with round female connectors, 
towards the right front tire.  One was labeled 5, which the schematic 
shows going to CB-1.  Was it mounted up there somewhere?  Anyone have a  
picture?

Thanks.
