Your instrument panel

As wigglyamp states in post 42, the CBs should be grouped otherwise you get long unprotected wire runs which are a fire hazard. Well, unless done in extra thick cable which is itself CB protected upstream.

I wonder what happened to Robin_253’s project? He posted several threads about extreme difficulties with the installer.

This is my post-TKS-installation panel, with the TKS control unit fitted, with great difficulty, behind the LH yoke. I also put in an Aera 660 in the LH yoke, which makes a very good GPWS box, wired into the AUX input of the intercom and with its display rendering terrain pretty well (if you zoom it right, which it seems to always need done manually)

In theory I should be re-doing the centre stack for 2×IFD540 or GTN650+750 (so I can get LPV, and flight plan transfer over wifi, basically) but can’t stomach this right now, after some massive problems with a supposedly high grade installer a few years ago. I could also do it DIY (I have sources for both Avidyne and Garmin boxes, even brand new) but it would need a heated hangar for a couple of weeks. Also the centre stack won’t come out at all easily (due to various people, starting with Socata, having run wires directly into it) so it would all have to be done from the front, which is possible but tight.

I also had to re-do the whole CB panel to fit several new CBs in (not just the TKS one but also the ADL150 and a few others) so all the CBs had to be reinstalled on a different pitch. It was done with metal strips to cover the old holes. This kind of work is really difficult to do in a hangar (especially an unheated or poorly heated one) unless there is a great workshop next to it, so as much as possible was done at home.
