ELECTRICAL CONNECTIONS

Disconnect vehicle battery before making any electrical connections.

Electrical connections to the unit are made using a removable terminal block plug located on the back. A label on the unit identifies the terminal function. You should install the connector on the unit before wiring. If the unit needs service the connector can be easily removed without unwiring the connector.

The power supply of the unit must be capable of delivering peak currents up to 50 amps for adequate short circuit protection and reliable operation. The preferred source is directly at the vehicle battery. The unit is internally fused.

Attach leads by stripping 3/8", inserting into connector and clamp by tightening screw. Make sure the screw is tight and the wire can't be pulled out. Failure to adequately tighten the screw can result in improper operation or burning the connector and wire.

Wire Size and Termination - The diagram shows the minimum wire size used for each connection, along with recommended lead color. If the wire is longer than 10 ft. use the next larger wire size. Use only high quality crimp connectors for installation on the vehicle.

Auxiliary Input Connection - The Auxiliary Input allows activation by an external source of either the Horn or Man/Phsr function. The adjacent diagram shows three connection

examples. See the INSTALLER- SELECTABLE OPTIONS section for programming details.

NOTE: Permanent disconnection of the vehicle horn is NOT recommended.
