I just added a lighting dimmer to my Icom A200.  I didn't wire the 

dimmer circuit initially, and it was really annoying to be completely 

black on a dark night!  Anyway, I found this document on the 

aeroelectric.com site:



http://www.aeroelectric.com/Installation_Data/Icom/Icom_A200-210_Wiring_D.pdf



At the top of page 2 there is a representation of the connector at the 

back of the tray labeled "Wire Entry view of Connector" that shows pins 

A and 1 on the left side of the connector.  The issue is from the wire 

side of the connector pins A and 1 are on the RIGHT side of the 

connector (the symbol is labeled backwards).  The Icom installation 

document has the same connector representation and it is labeled "Front 

view" which may confuse someone.  This "front view" refers to the front 

of the radio, not the front of the plane!



If you take the radio out, sit in the pilot seat and look down the tray, 

A and 1 are indeed on the left side!  So I think either the symbol is 

labeled backwards or it should read "Radio View Of The Connector".



Just to be clear, I added the power line from my dimmer to pin B. Laying 

on my back under the instrument panel (wire entry view of the connector) 

I added that wire to the top row, second from the RIGHT. And by the way 

the dimmer circuit works great, so I'm pretty confident that I got the 

right pin!



Sorry if this is nit-picky, but I don't want someone to blindly follow 

this document and get things wired backwards! (not that I have ever done 

that myself!).  The document seems to be seven years old, so maybe I'm 

the only one confused!



This document claims to be for both the A200 and the A210.  I can only 

speak for the A200.



I hope this helps!

   I believe you're right. I've updated the

   Icom installation data to include service,

   installation and operating manuals.

   I also reviewed the Molex philosophy for marking

   wire locations in the connectors . . .



  http://aeroelectric.com/Mfgr_Data/Connectors/Molex_Waldom/A200slash210.pdf 



   and all the documents agree with your observations.



   I'll go dig out that drawing and correct it . . .

   as soon as I get a really big hole in the

   side of my house plugged with a new patio

   door.



   Thanks for the heads-up!!!
