Changing out Sony System - help please

[05ModPod]

Hi.

We have the CDX-F5000 in the 05 CCD and we purchased a take out at Airstream factory a Sony MEX-R1 that is supposed to be an upgrade from the F5000.

I need to find the Audio wire harness female end that that goes into the back of the white male connector on the unit.

Any recommendations for a Sub woofer, CD changer and digital TV package that can hook into this unit?

I am heading to the states in three weeks so any ideas on where to shop too would be great.

Also anyone mounted a TV in the 22' CCD where would be the best place? I am thinking on the closet wall on the bedroom side thus it could swing out or on the kitchen side of the closet. Either side would probably work. Any hints???

Thanks
