Brief Description:  Throttle PTT; pitot heat connector

I disassembled the existing grip on my throttle grip, and began changing out the stock wiring with something a little more lightweight. The stock "Fatboy" riflle grip contained a massive, 7-conductor coiled cable which, while it would certainly serve its purpose, it a bit of overkill for my installation. I will replace this cable with two 22 AWG wires, one of which will be grounded someplace near the throttle quadrant.

A while back, the connector that attaches to the bottom of the heated pitot tube crumbled without any provocation, and I bought a new one. Today, I prepped the connector for installation in the left wing as soon as it comes off the airplane. By the way, these connectors must be, pound-for-pound, one of the most expensive parts of an airplane. This 1-1/2" piece of phenolic/plastic costs $170 plus shipping, and they are backordered for three months. Yikes. Don't break yours.
