Guys, I must be doing something wrong.
I installed Wolo horn to driver's side brackets. Connected Toyota horn connector with two wires onto Wolo horn positive terminal and ran a ground to the sheet metal to the Wolo horn negative terminal.
Horn works but when I arm the alarm, it just goes off buzzing the medium tone droning noise.
Should I have spit the Toyota connector with two wires into "+" and "-"????
Wife is not happy.
Help?
