Purchased 3 ground braids from B&C. They are 2 AWG equivalents. Two go from the thru bolt of the FOT ground point to the engine block. The other one ties the thru bolt to the negative battery terminal. I had fabricated a 2 AWG wire for the battery lead, but the braid is more flexible and easier to work with with the engine already mounted. (This entry written 7/17/2016. Date of entry matches dates on the pictures. No estimate of hours to install the braids.) Sometime after the FOT was populated with ground leads, I realized I should mounted the FOT a lot lower to reach it more easily once the final skin is on the fuse!
