Yes, I know exactly what you mean. It is common to used the shield as a conductor, but it is also common to use the shield as a......well..., a shield. The latter is a true shield and best for protecting the wires from noise (EMF).
When shielding it is common to ground only one end. It is all good and the PS engineering guys know there stuff, just follow the directions and ground the shield at the unit only per note 4. If you make it this way and isolate the jacks from aircraft ground (per note 3) you will have a noise free system. Multi point grounds is the curse of a noise free system. That is why the sheild and jacks all ground to the unit, not the airframe.
The harness is a pain, but it will be worth it. My DRE 244e for my RV-7 came with a harness, thank goodness. I wired a PS Engineering in my RV4. Making the harness was a little pain, but it is not as bad as it looks. PS Engineering is Good equipment and loved min for the +600 hours I flew it. You will like it. G
