Avic Z1 in 03 ML350 Inspiration D2B only Help

Hello,
I just picked up an 03 ML350 Inspiration and I'm getting ready to install a Pioneer Avic Z1 (from my old car)
But I'm running into a few walls, and could really use some help.

I have the VW Harness and was all set to go when I discovered that my MCS has the pins for line level audio output, but the harness does not have the wiring.

The audio is routed to the amp only by the D2B optical.

A) Is it possible to run new lines from the Bose Amp to the harness.
Is there a non-optical audio input on my model (info below)?

B) Does anyone have a pin-out chart for the Bose Amp?

C) Would I be better off bypassing the Bose Amp, pulling back the harness, tapping into each speaker line, and feeding them directly from the new HU?

Thanks a million for the help.

I can't wait to get my XM, Nav. and Ipod back up and running

Got it up and running.

Bypassed the Bose amp completely.
Pulled back the Bose harness, tapped into each speaker's lead and ran them straight to my HU's output.

Avic Z1's Internal amp is sufficient.
Sound quality is decent.
Sufficient bass without running the sub.

Colors were alittle odd at the Bose Harness
Used pins:
23 Pnk L/R +
15 Org L/R -
25 Pnk R/R +
17 Org R/R -
21 Blu L/F +
13 Grn L/F -
22 Blu R/F +
14 Grn R/F -

Thats it

Nav works perfect and looks beautiful in there.
