Ground point

[PIN 37]

Hello all, I am finalising wiring on my 7, I am wondering where and how people have put the firewall ground point. I have done a search but didn't get anything that tells where and how to make the ground point. A picture would be great,

Lots of folks use a "forest of tabs" like this one from B&C:



Here's some pics of a typical install. Cockpit side of firewall:



And engine side:


The B&C pics show tabs on both sides of the FW but I only put tabs on the cockpit side. On the engine side, I ran a braided cable (also from B&C) from the "forest of tabs" thru bolt to the engine.
