Snoopy / others-
It appears that all the cables between power point and base are low power, would a "molex" connector 12 pin work? I have seen these used in audio cabinets between equipment and a patch panel, so I think this might work. Just a little solder work.

Intention:
I would like to have a short cable off of the base/radio that can pass through sunroof, and run the cables up through the pillar/roof.

Thoughts?
