I bent the one end of the battery-to-master relay wire up ninety degrees. I tightened the copper bars between the two relays.

I positioned the oil line in place with Adel clamps and screws across the top of the firewall recess. I drilled out the temporary pop-rivets on the fuselage skin and the firewall.
