Default Re: Cigarette lighter wired to ignition

You can connect a wire with a 20-25 amp inline fuse to the red wire at the UHJB. inside the car cut the normal power feed to the cigarette lighter and tape up the end that originates at the black connector as it is always HOT. connect the lighter and whatever else to the new wire from the UHJB. If you wan to switch it then install a 30-30a rated contcat relay with a sufficently high enough coil resistance to not excessively load the ignition switch and connect coil control power from IGN-3 switched side. Ground coil to car frame, usually the H brace next to the radio on the left side. The ignition switch drawings are in my photo gallery.

REWARD EXCELLENCE!
