Note: To power the MDU, use one of the two power cords provided
(See Page A3).

• 12V Power Cord with In-line Fuse and Cigarette Lighter Plug:
For connection to 12-volt vehicle accessory outlet (cigarette lighter

Fuse box hard wiring is recommended. Use this configuration to

this connection yourself, contact a professional installer. Cobra

occur as a result of improper installation.
On a negative grounded vehicle:
1. Connect the positive wire [marked with a tag (+)] of the DC power cord
to an accessory 12V fuse that is controlled by the ignition switch
(Figure A).
2. Connect negative wire (-) to a chassis ground location (Figure A). Body
paint may need to be removed to assure a good ground connection.
