Default GTX 335 Wiring

I'm in the process of working on my schematic and building the harness for my GTX 335. I think I now have most of it figured out but I wasn't sure about the need for the temperature probe.

Do I need an OAT probe just for the transponder? I'm thinking the temp data should come from the GSU25 which has the G3x OAT probe but I can't find anywhere that it actually says this is the case.

Any help on this would be appreciated.

Joop,

Thanks, yes I have that GSU25 serial port connection.

Walt,

Care to share what I am giving up if I don't have the probe, if anything?

With a G3X you're not giving up anything, the OAT allows the xpdr to figure density altitude is all, the G3X already has all that.
