Finished the lower pass thru as per instructions. Put the firesleeve and clamps on both. This is as far as I can go until I run the wires.
Made a grounding lug from 1/4 x 20 all thread and put it in firewall at location suggested in plans. Main battery ground will connect on engine side, Other grounds will be routed to the lug on the back of firewall.
