[GreenKeys] W.U. LESU

[John W9DDD]

I'm about to post a drawing that has physical location of parts.  
C terminals (aka TS3) are at the top back of cabinet covered by black insulating covers.
I think C1 & C2 would be the place to key the loop with an external contact.  To use an externally powered loop some jumpers would need to move, all depending on whether modifications have already been made. 

John, W9DDD
