Wire Size and Termination - The diagram shows the minimum wire size used for each connec- tion, 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 acti- vation by an external source of either the Horn or Man/Phsr function. The adjacent diagram shows three connection exam- ples. See the INSTALLER- SELECTABLE OPTIONS sec- tion for programming details.
