I replaced mine on my 2016 with this. Don’t know about the 2018’s.

Nice to get good feedback on an electric only installation. Could you share some installation info? Where did you install the horns, place the switch, etc? I might attempt this if I can get a decent horn w/o tapping into my air system. Thanks.

I did away completely with the roadrunner horn. Just used the same wires going to it. Placed the horns under the chassis on a bracket for cables. Button on steering wheel activates air horn through existing relays. Biggest problem is keeping the grands out of the cab when camping!

May have to give this a try. I think I may install separately and keep the factory horn for in-town use. Definitely understand the grand kid issue

Previous owner put a switch in mine. Up it activates, through steering wheel button, both beep beep horn & air horn. Down it’s just the “city” horn.
That works pretty well.
