Direct Connection of the 12-Volt Power Harness With
In-Line Fuse Holder
Use this method when you want a direct connection to the
vehicle’s electrical system. Leaving the in-line fuse holder intact,
cut the cigarette lighter plug from the cord and strip about
4 inches of the thick, black insulation away from the three wires
inside.
Connect the red wire inside to the vehicle’s ACC (accessory
circuit). Connect the yellow wire to the vehicle’s constant 12V
power wire, and connect the black wire to the vehicle’s ground
circuit. The best place to make those connections is in the harness
that provides power and ground to the vehicle’s radio.
IMPORTANT: Replace the in-line fuse only with one of the
same type and rating.
