Using an Adapter Harness

If you are replacing an existing stereo, or if your vehicle has been factory-wired for autosound compo- nents, you might be able to use an adapter harness to connect the pow- er and speakers. RadioShack stores sell adapter harnesses for most ve- hicles.

Follow the directions that come with the adapter harness to temporarily connect the ground, power, optional components, and speakers. Then go to “Connecting the Antenna” on Page 9.

Connecting Ground, Power, and Optional Components

Follow these steps to connect the supplied harness with the 14-pin connector to ground, primary and memory backup power, and optional components.

1.Disconnect the cable from your vehicle’s negative (– ) battery ter- minal.

2.Connect the black GROUND (–)wire to a chassis ground, such as a metal screw attached to a metal part of the vehicle’s frame. Be sure that the screw is not insulated from the chassis by a plastic part.

3.Connect the red POWER LEAD (B+) wire (with in-line filter and fuse holder) to a point in your vehicle’s fuse block that has power only when you turn the vehicle’s key to either the acces- sory (ACC) or START position.

This connection turns on the ste- reo when you turn on the ignition or turn the key to ACC, and turns off the stereo when you turn off the ignition. This pre- vents your vehicle’s battery from being drained if you leave the stereo on when you turn off the ignition.

4.Connect the yellow CLOCK MEMORY wire (with in-line fuse holder) to your vehicle battery’s positive (+) terminal or to a point in your vehicle’s fuse block that provides a continuous source of 12 volts.

This connection provides contin- uous power for the stereo’s
