I am installing a full Dynon Skyview panel. I decided to purchased the wiring harnesses with a view to purchase the components a bit later.
This relates to install of:
SV-COM-T8
SV-Intercom-S2
CV-COM-Panel

I am using the SV-HARNESS-INT (102791-000) Hook-up table to connect to the SV-COM-T8 but the cable pin call out is to SV-COM-425, the SKYVIEW HDX WIRING DIAGRAM. The Intercom table does not show the Pin call out for the T8.
RADIO MIC OUT
RED RADIO MIC OUTPUT 25 SV-COM-425 Pin 1
BLU MIC GND GND SV-COM-425 Pin 2
YLW RADIO MIC PTT OUTPUT 12 SV-COM-425 Pin 5

RADIO AUDIO INPUT
WHT RADIO AUDIO INPUT (HIGH) 14 SV-COM-425 Pin 10
WHT/BLU RADIO AUDIO INPUT (LO) GND SV-COM-425 Pin 9

Using the HDX Wiring I have deduced the following and keen to see if anyone else agrees this is correct or what it should be:

RADIO MIC OUT
RED RADIO MIC OUTPUT 25 SV-COM-T8 Pin 23
BLU MIC GND GND SV-COM-T8 Pin 9
YLW RADIO MIC PTT OUTPUT 12 SV-COM-T8 Pin 15

RADIO AUDIO INPUT

WHT RADIO AUDIO INPUT (HIGH) 14 SV-COM-T8 Pin 2
WHT/BLU RADIO AUDIO INPUT (LO) GND SV-COM-T8 Pin 1


Any help appreciated, If Dynon read this is would help to produce and Intercom Hookup for Com-T8.

I don't know what a CV-COM-Panel is. I assume you mean the control head for the radio. Just at a glance, there may be one error, maybe more. Everything you want, except wire colors, is on page 11 of the SV-INTERCOM-2S Install Guide.
Thanks, the confusion from my side is the wire colour call out from the Dynon Intercom wiring document defines the colours but a different pin call out as its for a COM-425 opposed to the COM-T8.

Thanks, :) looks like I got it right. Note that the CM_T8 is D25 connector.....this confussed me as kept looking at the Com-425 which is a D15 connector. Well according to the docs its is.

That's interesting. I just copied that over from the intercom installation guide. I never noticed they had the connector improperly labeled. I'll go back and fix that later, and then repost the diagram. I might also add the transmit interlock. And you are correct that the 425 uses a D15 connector.

This has the correct connector identification. I did add in the transmit interlock connections, but took them back out when I realized they aren't necessary when a Radio Select switch is installed on pin 12 of the intercom.
