Guys,
I won't be using my backup EFIS D6 for Altitude Encoder data...instead I have a GRT EFIS that I have wired to send altitude data to my Trig T-22 Transponder.

So should I just cap off the Alt. Encoder wires on the D6.  These are DB25 Pins 13 (Encoder serial transmit) and Pin 21 (Ground).

Thanks for any guidance.
