Enlarged the passthrough on the firewall for the EIS sensors to 1" from the 3/4 inch made by the stepdrill. Used stainless pop rivets to attach the fitting on the firewall for the pass through. I used a plastic grommet inside the fitting to protect the EIS wires fromt the sharp edges of the firewall.
Also made a 7/8 opening with a Greelee punch on the bottom of the firewall so the starter wire and alternator B lead wire can pass through the fuselage. I used a zinc electrical connector at that location.
Removed the battery tray. Marked the alternator cable and the starter cable to the correct final length after passing them through the firewall and attaching them to their fitting points.
Installed the ANL fuse block on the firewall with two #8 screws.
