Easy day as I finished using the multimeter to verify each wire for the EMS-220's sensor harness and then separated them into firewall forward and aft bundles. A lot of wires aren't used, but I hesitate to remove them from the connector as I don't want to possibly damage an adjacent wire. I plan to make them shorter and protect the ends with a piece of heat shrink. I also need to figure out what to do with the many ground wires. The instructions aren't clear as to whether they're unused or should be grounded. Probably unused or there would be a grounding symbol on the drawing. I'll verify with Advanced Flight.
