Suggestions for "laying in the wiring harness"

If you upgrade to the wiring harness that VP can provide you, here are a couple of observations.

A) Make sure you know how the connectors work and prove to yourself that you can unlock one and redo it without damaging it. Do this prior to "laying" in the harness

B) I'd suggest this order for doing the wiring around the VP harness

  • Lay in the harness
  • Group wires together that go to similar locations within the airframe
  • use tape or tie wraps to loosely bundle the groups mentioned in item 2 above
  • Determine penetration points where needed and basic wiring attachment points (this won't be all of them and don't do all the bundling and tie-wrapping yet)
  • Determine your ground points and install the ground connection blocks
  • "lay in" the ground wires parallel to the power wires from the harness and use the similar paths, penetrations, attach points, etc

C) After step (B) above you should have the basic power harness installed. Now focus on the other "signalling" functions (e.g. flaps, trim, switches, stick grips, etc)

D) Finally install and connector all the other functions (e.g. autopilot signals, serial inputs/outputs, audio, etc)

Some of these steps can be swapped depending upon how complex your equipment is, but the (B) step in the order specified is what worked the best for me.
