Joe (& Marty),

Cording and wiring diagrams for the SCR-193-(*) are in TM 11-273.  4/12/41 
edition covers -A through -E.  5/02/45 covers -D through -U + -KB & -KW.  The 
suffix letters are vehicle specific, a carryover from the pre-war practice of 
assigning specific letters by vehicle.  I think that stopped with the SCR-193, 
after which it was a generic radio set to order, plus an installation kit by 
vehicle.

The -A, -B and -C models were set up to use Control Box BC-321.  The -B also 
used BC-309.  D and higher show no control boxes and no usage of the 4-pin 
PL-74.

The -D and higher cording diagrams differ only in cable nomenclature and 
length.  I can scan the necessary pages.  If you are doing a setup for a specific 
vehicle, let me know which.  Or if you have and want to use BC-321 or it and 
BC-309, let me know.  Or if you have any single-ended cables let me know the CD 
number(s) so I can be sure to scan the page that lists them.
