I'd like to install an air horn in Schultze. I noticed that there is a "blank" to the left of the e-brake; is it possible to install a switch there that would activate the air horn?

I want the air horn to operate independently from the OEM horns...for special circumstances vs. being used in conjunction with (or in place of) the OEM horns via the steering wheel.

Thanks!

 

I have just recieved my Griot's Air horns. I want to install them instead of the OEMs. Need some advice....HELP!
