Cut and labeled wires to go from teh landing and taxi light switch to the left wing root under the pilots seat. Worked out the connections to the switch. Researched source for the Oddessy 680 battery. Bpought one from Tri-State Battery. The battery location should fit under teh passenger seat behind the main spar. Researched source for a good quality crimper for the electrical connections. Bought one and a supply of terminals and associated wiring supplies from "The Terminal Store".
