Since I'm a rookie at this, I just re-read the section in the Aerolectric Connection about Audio Panels. The answer to this is not in there. I am having trouble with the naming conventions provided by two different vendors in their documentation. I believe that they are calling the same things by different names. That would be a great injustice on their parts if intentional, so I am sure that it is just my inexperience playing the major role here. Anyway, for connecting the COM to the Audio Panel, here are the pertinent connection labels and pins:
On the Garmin SL40 COM:
Headphone - 14
Audio Ground - 13
Mic 1 - 8
Mic Ground - 7
TxKey - 4
On the PMA4000 Audio Panel:
Com 1 Audio HI - Top-19
Com 1 Audio LOW - Top-7
Com 1 PTT - Bottom 22
Com 1 Mic Audio HI - Bottom 21
Com 1 Mic Audio LO - Bottom 9
What I'd like is for some to confirm that they match up (are connected ) as follows:
Headphone - 14 to Com 1 Audio HI - Top -19
Audio Ground - 13 to Com 1 Audio LO - Top - 7
Mic 1 - 8 to Com Mic Audio HI - Bottom - 21
Mic Ground - 7 to Com 1 Audio LO - Bottom 9
TxKey - 4 to Com 1 PTT - Bottom - 22
Thanks for suffering thought these details with me. It seems that PS Engineering refers to the ground as "LO" consistently.

I'm just about to go through the same thing only with an SL30. If you call Tony at Stark Avionics I'm sure he will have the correct answer. He has been very helpful in my other endeavors so far.
