24 inside X 24 FWF. That looks like it will fit somewhere around the battery Starboard side to keep the ground as short as possible. Thoughts?
Ooh, another thing, Larry, I don't know what kind of avionics you are planning, but consider a 48-tabber on the cabin side if you have a lot of electronic goodies. My fairly complete All-G3X system used every single tab--not an exaggeration. When I ran the 48th circuit, I broke out in a cold sweat hoping I didn't forget anything.

Since I have few electronics on the firewall side, I did not put a tab forest on that side. Simply didn't feel I could justify it. Still have the block sitting on my shelf unused.

Also, pay attention to where you mount the forest. I just picked a convenient spot on the right side, right above my battery box. Of course, this means I can't slide the battery up and out of the box anymore. I need to take the whole battery box off the firewall to remove the battery. Don't do what I did.

Hopefully 24 is enough. Pretty basic glass. However, I'm using the Advanced Control Panel. It has power and ground and handles the power, audio and data circuits. FOT is installed roughly center above the recess. Area above the battery is pretty clear. Hopefully the battery will go in and out!

You can double up grounds on similar low amp circuits. My harness from stein had many avionics grounds going to singular fast on connectors.

My location seems to work as far as battery removal. I was just working on adding the ground wire yesterday. I'm still not sure if I'll leave any of the forward side tabs but for now here is a picture of a test fit of what I have.

I did the 24/24 fwd and aft of the firewall. Lots of tabs available inside but I also doubled up on several. Nothing connected to the fwd tabs but they are there if needed for future.

Off topic: My engine has a horizontal induction but I opted to install a 90 elbow for the AFP fuel injection. Was fairly easy to get all cables hooked up and keep clear of the Vetterman trombone exhaust. I have a video of the installation on Google Drive, if anyone wants to see it.
