Garmin 330ES coming out: 335 going in

The plan is to install the stand-alone ADS-b out 335 transponder in place of my 330ES which would require a WAAS GPS input that I don't have now. I also ordered the rear mounted encoder. Connections are to GRT Horizon WS displays and a Garmin 430 (non-waas).

Have others done this swap? Any words of wisdom or schematics of your setup?

I emailed you a response to you private email. Please read. We have similar systems and reasons for the swap out. One thing I didn't discuss in the email is the programming of the 335. With that I have some "real lessons learned" to share with you. Send me another email and I will give you my phone number.
