I looked through the 4 manuals i have and the only thing i saw that even 
came close to what you would need was on a schematic for the system.  TO 
AN 16-30ART13-4, Fig 8-43, 8 March 49/Rev. 15 Sept. 1954, AN 
16-30ART-13-3, August 1954 and AN 08-30ART13-5 also known as NAVAIR 
16-30ART13-5, 20 Jan 1945/Rev. 15 July  1954 for reference material.

Looks like you could use either the connector at UG-6/U in place of the 
original C-87 or pick off the wires as needed at TS-2 where you could 
also wire in COntrol panel C-405/A.  I checked all 4 of my ART-13 
manuals and saw nothing about the Yardeny tuner as far as attachments go.

Must be in some manual other than those i have cause in these three 
there isn't a mention of that.  WOnder if there was an ARC paper that 
showed the modification to the receiver and what external wiring was 
needed to make it function.

Another oddity i saw is that in TM 11-692B-2/ AN 16-30art13-3 they talk 
about and show a C-405A control head.  Nothing about the C-740.  In TO 
08-30ART13-5 they show the C-740 and nothing on the C-405 although they 
look identical to me.  Didn't verify wiring but both are designated as 
Pilots control panel.   Both TO's are dated about the same time frame 
1953 and 1954.

I had an R-XX receiver here that was modified for the tuner but i don't 
recall any connector for external wiring.  Hmmmmm.  Maybe my instant 
recall isn't functioning as i think it should.  Michael!
