The kit comes with ample aircraft wire, but it's all one color -white-. I want to color code certain circuits so I ordered several different colors in various gauges. I've taken the time to organize all of the electrical hardware since I'll be starting the wiring pretty soon. Many of the items shown in the second photo did not come with the kit, but were purchased to supplement the basic items that were furnished. Not shown are various sized Adel and aluminum AN line clamps for suspending the wire/sensor runs. When using the AN alum. line clamps (shown below) for the various engine sensors, I plan on inserting the sensor wire through a silicon sleeve/tube to cushion it in the clamp. This style of clamp should be very tolerant of the heat generated by the engine.
