12 volt connection point ?

[c240yaz]

I was thinking of trying out the old 27Mhz CB radio, but was wondering where to get an easy 12v connection and earth, without pulling the dashboard apart, and wires all over the place. (Will use an external mag mount for the ariel).

Any electric experts got any ideas on best 12v and earth connection point ? 2002 C class.

Remove dashboard endcover from drivers side and take power from the fuse area with a new fuse holder.

Generally ground is really close to the seat on the floor panel. Remove door sill and lift up the corner to reveal a substantial gound plane bolt. Another bolt is at the kickpanel area on both sides.
