I'm likely going to do a mod that requires modding my horn (Auxiliary bullhorn using the horn signal with a mode switch when the switch is flipped) and I need to know, is the horn positive or negative switched?

 

Upon further inspection it seems this is not worth it. I'd have to cut both horn wires, wire in two auxilary relays to have the horns switched, also take said horn wire and tap off it before the relays to the switch in the cabin and it's just a mess because of this TIPM hiding all the relays inside. I'll stick with a momentary button.
