I checked the page before posting, and no, probably not, though one 
never knows. Anyway, my control unit is (IIRC) a three-unit wide, 
straight voltage type controller, whereas the MB, MC and 1B engines 
employ a two-unit wide pulse-width modulation type controller, if I have 
understood correctly.

The controllers should share a few inputs, but their locations are 
probably different, so I'd need markings from the control unit itself 
(if it has any) rather than ordered numbers on the relay plate :(

Thanks anyway.
