how can I hook up a horn on my H farmall, I have a 2 prong momentary switch,and a horn that has a pos. wire and ground wire, how do it do it from the 12v battery. thanks

Hook the ground wire from the horn to ground.
Hook the Positive wire through the switch to 12 Volts.
This assumes the switch has a high enough current rating.
If not, you may need to add a relay.
One thing to consider is whether you want battery 12 volts or
switched 12 volts. Horn won't work with the key off if switched.

You're probably gonna need a horn relay if you use it much about $10 to $15 unless you have an old car or truck in the fencerow
