I have searched the forums on how to hook up additional power devices such as cameras, radar, GPS etc. I also see that you can buy cigarette adaptors that can simplify the process.
My question is, is it possible to hard wire (no need for a connection kit) a device (with an inline fuse) into your wiring system. The device is drawing 9 volts DC do I need to put a converter in line? Or will it simply draw the voltage that it needs?
