This is standard stuff for tough mobile applications, Stephen.
Strain-relieving is about supporting a soldered connection to prevent 
fatigue failure at the point where the solder ends. A helicopter is a 
great example of an environment in which a solder joint, with wire 
that's free to vibrate, can come apart in hours.

 Correct- support flexing wires about every 4". One of the most critical is the wire(s) for a crank-fired ignition. One Pantera owner's high-dollar super-ignition system broke two pick-ups- with factory strain-reliefs-  in a 500 mile run to 'Vegas and back. In the installation, there was a 12" long unsupported section next to the harmonic balancer. He had extra sensors drop-shipped to him on the way from the embarrassed mfgr and used all 3 on the trip. NOT a happy camper that weekend!  FWIW- J DeRyke
