[VHFcontesting] TS-850 Amp Keying Output

[DUGAS, JASON A. (JSC-EP) (NASA)]

I'm trying to get my TS-850 interfaced to a 2m transverter.  Can someone
tell me what connector/pins are the two that get shorted together when I
press the PTT button?  Also, where can I get the mating-half for the
connector that is used?
