How do i wire a 12 volt cigarette lighter plug on to a device like a c.b.radio?
On American cars the positive lead from your cigarette lighter is in the center of your socket. The adapter plug has the positive lead on the tip of the adapter and the negative lead on the side of the adapter. You need to use a volt-ohm meter to find out which wire comes from each lead. (You may be able to open the adapter and follow the wires that way).On the c.b. radio the positive lead should be red. This will connect to the positive lead on the adapter. The black lead on the c.b. radio is the negative lead. This will attach to the negative lead on the adapter.P.S. Usually the adapter will have a fuse built into it to protect from incorrect wiring.
