Quick job tonight, shortening up the wiring for the outside air temperature probe. Because I installed the probe in the air vent instead of the wing, I was able to shorten up the wiring considerably.
The wiring is a 3-conductor braided cable, and the braided portion of the cable needs to be grounded. I used a solder sleeve with attached wire to quickly solder a ground wire into position. I had plenty of spare pins and connectors, so I was able to install pins on the wires and wrap it up quickly.
