I reassembled the D37 shell for the EMS. There were 2 unused wires which I did not remove. One was for heated pitot status and another was an optional external alarm light—don’t think I’ll use either, but left them just the same. I cleaned up the wire run from the gear tower to the firewall-still need to add the mag p leads, but then should be done in that area. I began connecting the MAP sensor wires. I crimped the terminals with pliers, then a soldered the connection. I wasn’t going to buy another crimper for 3 crimps! Installed the pins and finished the connection.
