Hello all,
I am sure you can assist me with this. I have recently installed ( stuck on windscreen and connector into cigarette holder ) an incar video camera. All is working nicely. Now I wish to hardwire this from the fuse box and eliminate the cigarette connection. I want to introduce a switch, so as to control when I want the unit powered up and stop the constant draw from the car battery.
DOES it matter if I break the ACTIVE lead or the GROUND lead, which is the better one, or doesn`t it matter.
I just have this unconscious thought about possible sparking.

Thank you in advance
John
