From: "Dave_A" Essentially, it's supposed to support this feature (bypassing the vor/loc converter) but I can't find a pinout that lists how to get this signal... I'm trying to figure out how to hook up a CDI that takes composite input, as the only ones that don't are the really expensive Collins and King models.

Luckily, it came with a harness. Unfortunately, it did not come with installation instructions. The harness has a 23 pin connector on the transponder side and a 15 pin connector on the altitude reporter side. Three heavier wires (I believe 16 ga.) are cut to about 4 inches in length, coming out of the 23 pin connector. I am assuming these are the power leads, red (+14V), black (Grnd), and yellow (?). That's my question; what should this yellow wire attach to? It comes out of pin #12 on the connector. I can't seem to find any wiring instructions on the internet for this 23 pin transponder. ________________________________ Message 3 _____________________________________ Time: 03:59:52 PM PST US From: "Stan" Subject: RE: Avionics-List: Narco AT-165 Transponder wiring question Traditional avionics color coding makes the red wire power, the black wire ground, and the yellow wire the dimmer. Here=99s a link to the AT-165 installation manual. It says that pin 5 is +13.75 V input, pin 11 is the 14 V dimmer, and pin 12 is ground. Perhaps the yellow wire is going to pin 11 instead of pin 12? And I think it may be a 24-pin edge connector, with 12 pins on each side. Hope this helps you get everything sorted out! http://www.aeroelectric.com/Installation_Data/Narco/narco-at-165-install. pdf From: owner-avionics-list-server@matronics.com [mailto:owner-avionics-list-server@matronics.com] On Behalf Of N262TH@comcast.net Sent: Monday, January 02, 2012 3:24 PM Subject: Avionics-List: Narco AT-165 Transponder wiring question I recently purchased a nice used Narco AT-165 transponder from a third party.

All of their transponders use the same tray and pin connections. So pinout for AT50 or 150 will work.
