1.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 frame by a plastic part.

2.Connect the red +12V to IGNITION wire (with in-line 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 accessory (ACC) or START position.

This connection turns on the stereo when you turn on the ignition or turn the key to ACC, and turns off the stereo when you turn off the ignition. This prevents your vehicle's battery from being drained if you leave the stereo on when you turn off the ignition.

3.Connect the yellow +12V to BATTERY wire (with in-line fuse holder) to your vehicle battery's positive (+) terminal or to a fuse that provides a continuous source of 12 volts.

This connection provides power for the stereo's components (such as the clock), and continuous power for the stereo's memory when the ignition is turned off.

4.Connect the blue/white AMP REMOTE TURN ON 500MA MAX wire to any optional equipment designed to run from a switched source that you want the stereo to turn on and off (such as a booster or a power antenna).

This wire does not provide power to the components. It simply turns them on or off. If you do not use this wire, secure it with a wire tie and do not let it touch metal.

Note: The optional equipment must be designed for use with a switched power lead.
