PCR2500 INSTALLATION INSTRUCTIONS/WIRING DIAGRAM Do You Need an Installation Kit? Inspect the radio opening as described below to determine if you need an installation kit. 1. Use the trimplate supplied with the radio to cover the existing dashboard opening. If it completely covers the opening, you can install the radio without an installation kit. If it does not cover the opening, you will need an installation kit (see page 4). 2. Check for sufficient space behind the dashboard for the radio chassis. Wiring the Radio 1. Place the radio near the dashboard so the wires can be led through the opening. 2. Carefully follow the wiring diagram, securing all connections with wire nuts or electrical tape. 3. Turn the unit on to confirm operation (vehicle ignition switch must be "on"). If unit does not operate, check all wiring until the problem is corrected, then turn unit off. 4. Adjust the AM Antenna Trimmer, located on the right side of the chassis, for optimum AM reception. a. Tune in a weak station around 1400 KHz on the AM band. b. Using a small screwdriver, slowly adjust the trimmer for maximum output from the radio. Antenna Connector WARNING! Never combine (bridge) outputs for use with 1 speaker. WARNING! Never ground negative speaker leads to chassis ground. CAUTION: Failure to wire exactly as shown may cause electrical damage.
