Installation Considerations

Be aware of the following installation considerations:
1. Turn the vehicle's ignition switch off during installation.
2. Connect both black leads to the same vehicle chassis point. This prevents possible ground
loop damage to the system should the ground point become bad.
3. Locate all fuses near the battery or the ignition.

Power Connections

Do the following:
1. Route the orange fused lead to the ignition voltage or battery voltage (see
"Ignition
2. Route the red fused lead from each radio directly to battery positive.
3. Connect the black lead from each radio to the vehicle chassis.
