2017 Sprinter Chassis, under a Thor Synergy 24' 2018 body. The standard 6 cyn Mercedes Benz diesel engine....
My problem is the standard horn sounds like a toot toot whistle. I would like to add or change it out for a two tube self generating air horn.
Does anyone know what and where the 12v power line is from the horn button to the actual horn?
To get at the horn, it looks like you would have to pull off most of the front end because it is hidden behind it, and I cannot find or see the wiring to the horn itself. Any suggestions?
