Push to talk button copilot?
 

Currently the ptt button is on the panel near the map box door.
Whats the best way to relocate button to the yoke?

I'm no avionics shop, but it sounds like you could run that pair of wires up your yoke on a coil-cord and mount a simple PTT switch. You could even use velcro like the old PTT intercoms. Heck, I've got three or four PTT switches lying around if you need one! The little red ones are the style I have. No matter what, it should be a fairly easy task.

For the interim I would use a portable PTT that Velcros to the yoke. In the future you may want to have your yokes refurbished at Sair and have them put the PTT and wires in

Those are great ideas thank you 👍

I purposely wired in the front right PTT on the panel above the glove box - that way passengers aren't accidentally pushing it. However, I carry a Velcro PTT in the map pocket in case pilot in RH seat wants to have it on the yoke, or in case the PTT on the pilots yoke fails - so it serves dual purpose.

The one I carry is the PTT-400, purchased from Aircraft Spruce (their P/N is 11-02072). Small and mounts vertical.
