I would like to hide the cables from the dashboard DVR and hook the DVR up internally to the power source. It's a trivial thing to do if you know what to lever and how brutal you could be with removing of the interior plastic parts. Unfortunately I don't know and don't want to have the parts hanging later out of the roof or the dashboard if I brake something.
Getting to the point: may someone please recommend a reasonable (work quality, pricing) electrician who could do this kind of job?
