Avionics Cost Question

For you avionics guys out there...what should it cost to have an avionics
shop install an audio input jack in my panel as an add-on to my
panel-mounted stereo intercom?

We have a Narco CP-136 audio panel, and a PS Engineering CD/Intercom.
I'm assuming the input jack has to "patch in" to the intercom somewhere.
(Frustratingly, a jack already exists for the back-seat passengers only.
It's a nice feature so that they can listen to their own music in back --
but we don't have the same option in the front seats.)

I would like to use this input jack to connect a portable XM radio
receiver or an Ipod-type device.

Thanks in advance!

It costs next to nothing if you do it yourself and then have someone look at
it (or not). If you have the intercom that I think that you do: music input
(L) is pin 14 (and the barrel on the jack), (R) is pin T (and the tip of the
jack) and then ground the jack to wherever all the shields are grounded. I
think that I have the pins if you can tell me what length wire you want, I
will make you one.

Thanks, Mike. I'm hopelessly ignorant when it comes to this kind of stuff,
so bear with me...

When you talk about the "pins" I assume you mean the pins on the back of the
intercom, where the wiring harness plugs in? Isn't the harness already
plugged into pin 14 and pin T? How do I gain access to those pins, so that
I may connect another wire to them?

Or are these unused openings in the harness, and you're talking about
installing these pins INTO the wiring harness?

Either way, the wires wouldn't have to be more than 24 inches long.

Pins 14 and T are only used for an external music input which you don't seem
to have so the pins should be unused. If this is the case you will add a
wire (actually a two wire shielded cable) that will go from these pins (and
ground) to the jack where you will plug in your MP3 player. You might want
to go to PS Engineering's site and download the installation manual. If you
look at the wiring diagram, everything will be clear.
