In positive ground vehicles the red wire goes to the chassis and the black wire is connected to the ignition switch.

Before installing the CB radio, visually check the vehicle’s battery connection to deter- mine which terminal, positive or negative, is grounded (pos- itive is the larger of the two) to the engine block (or chas- sis).A negatively grounded vehicle has its negative lead grounded to the chassis.

6Plug power cable into back of unit marked “Power”. Be sure to observe polarity markings.

7Mount the microphone bracket on either side of the unit (driver’s left) using two screws sup- plied. Bracket should be placed under the dash so microphone is readily accessible.
