Wayne:
My system on my RV-7 consists of an AF-4500EF and an 3500EM (connected via an ethernet box). My avionics package consists of a Garmin audio panel, 430W, SL-40 and GTX-327. I bought the Freeflight FDL-978-XVR ADSB unit with the TC978 controller, GPS and WIFI units from Walt Aronow at EXP Aircraft Services. I mounted the FDL units behind the baggage wall on one of Van's ELT mounts. The TC978 will be on the instrument panel. I am still in the process of working on the project so it's not operational as of yet.
I have a wiring diagram (Xcel spreadsheet) that Walt helped me with (including input from Freeflight and Rob at AFS). If you only have a AFS 4500 unit, it appears the only difference will be running the #5 serial output (pin 42 of the FDL-978) to the serial port 3 RX (pin 5 on the 4500) - (assuming it is available for you to use). Send me a note at dcw@mnwing.org and I'll send it to you.
If you have any other questions, just let me know. Also Freeflight, Walt at EXP, or Rob can help as well.
