This PLUG and PLAY harness allows you to integrate an aftermarket train horn to work with your original horn button in the steering wheel. When wired into an OEM upfitter switch or customer installed switch the factory horn will blow when the switch is off and the train horn will blow when the switch is on. Two connections will need to be made...
1- To an OEM upfitter switch or customer installed switch
2- To the power wire from the valve on the train horn kit
ALL CONNECTIONS ARE MADE UNDER THE HOOD. THERE IS NO NEED TO DO ANY WORK INSIDE THE CAB.
Fits 2023 Ford Super Duty Trucks
THIS IS NOT A TRAIN HORN KIT, THIS IS AN ADDITION TO A TRAIN HORN KIT TO ASSIST IN INSTALLATION.
