Installation Overview
Nothing Comes Close to a Cobra ® 5
Mount the MDU high on windshield to right of rear view mirror (Figure B).
The MDU must have a clear view through the windshield, be parallel to the
road (Figure C) and have clearance to snap into the “up” position.
Position the MDU for easy access to power switch, cable connections and for
mirror movement. Mount the MDU on the windshield close to the headliner.
(See page 7 for details.)
IMPORTANT: Do not block the MDU lens with the sun-shaded area of the
windshield (Figure D).
Heated windshields currently available on some vehicles (Instaclear for Ford,
Electriclear for GM), may block or weaken incoming signals. Consult your
automobile manufacturer.

Installation Overview
Mount Unit
Main Detector Unit (MDU)
Note: To power the MDU, use one of the two power cords provided
(See Page A3).
• 12V Power Cord with In-line Fuse for Hardwired Installation:
For connection to vehicle’s fuse box or battery, or
• 12V Power Cord with In-line Fuse and Cigarette Lighter Plug:
For connection to 12-volt vehicle accessory outlet (cigarette lighter
plug).
Fuse box hard wiring is recommended. Use this configuration to
provide a more discreet installation. If you are unsure about making
this connection yourself, contact a professional installer. Cobra
does not warrant any damages to the product or vehicle that may
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.
