After an enjoyable trip to Oshkosh this year when my lovely wife surprised me by telling the BOSE guy "They sound nice....We'll take 2!" left me speechless. They haven't been delivered yet even though we paid for them at Oshkosh(Another story)
The current headphone jacks are mounted on the sides behind the seats so it would make the most sense to mount the LEMO jacks right next to them. Here are a few pics to show my mounting ideas:

I am going to mount the Bose power jacks right next to the existing jacks. On the pilot side the tie down ring storage spot is kind of in the way but that is ok. If I have to remove the BOSE jack prior to removing the tie down ring that will be just fine. I will try to get them as close to the others as possible and hopefully that will let the tie down ring clear.
I do have some questions that I would like some additional input on:
My plan is to get the jack as close to the others as possible.
Then I will dress the shielded wires and solder them right on the adjacent jacks.
Q1. I wonder if the shields are grounded on the existing jacks?(somewhere on the other end? I didn't build the aircraft) Do the shields on the new jacks need to be grounded or because they will only be 6" long and won't be near any other electrical it won't be a problem?
Q2. The Adel clamp that is the strain relief for the existing jacks, should I get a bigger one to contain the new set of wires? Source? ASP?(Aircraft Spruce) Anyone know the size of the existing one? and how bigger I should go? (I'm not even sure how they are sized...)
Q3. If I buy a bigger Adel for the existing jacks, should I use the old clamp and put it on the new wires? Or who cares about a 6" loop of wire? If I add a clamp should I stack the two clamps on the existing bolt or drill a new one?
Q4. I need to get power and ground to the new jacks. Should I run both sets all the way forward to the fuse block and the FOT or would it be ok to crimp them together where they meet in the center tunnel or run one side over to the other and splice there and then run forward?
Q5. Looking at the jacks again maybe I need to just pull the wires from the shield and make a 2-4" loop and solder the phone/mic wires to the existing Jacks and then sneak the power and ground through the existing Adel clamp.
Thanks in advance guys, so nice to have the resources of this group available to us newbies.
