Horn circuit

95 yj installed a grant steering and the horn button sometimes pops off and the horn will blow until it melts down the horns(2 times already). After checking horn circuit it is hot all the time. I need to change it so it only works when the key is turned on. Any help.

The horn circuits are always hot. This is reversed than most circuits because normally the load/unit is always grounded, and then the hot is on a switch. In the horn it's reversed, the horn is always hot, and the ground is switched via the steering wheel push-button. This is because 1) you don't want current going through the steering wheel 2) you want the horn to work all the time.

You can bypass this by replacing the constant hot part of the horn circuit with an ACC circuit. You will need to tap in from any unit that is powered from it. I don't know exactly your '95 has, but my cigarette lighter only works when in ACC/Key-On/Run position.

For example, I have my KC light from the ACC circuit powering the KC Light relay, this is because I didn't want the light to come on when the Jeep is off. You will have to relay the horn if you're switching circuits btw. And the most important thing is to make sure whatever circuit you tap into can handle the additional amperage, you don't want to blow a fuse and lose the horn / radio when you blow the horn lol.

Hopefully someone with a '95 will chime in, I know for sure that the electrical systems vary from year to year, I can't give you a definite answer but that's the core of it.

I'm assuming there's a relay for your horn. Just tap the constant coil on it. Either 85 or 86. Cut it and route it to an acc or ign wire.

Unplug your horn wire out under the hood.

Then get in the Jeep and take the horn button off and turn it a 1/4 turn to the left. re-install and when it stops turning, push down and turn it a little more. The it will pop back up into the proper slot.

I installed a grant wheel in mine as well, and was having the same trouble. Figured out that I didn't have the horn button on correctly.

The 10amp fuse and relay is under the hood on the 95 model. One diagram I have shows it on the key, but it's not. Since i posted i got a new horn button and the little bumps to lock it in is 2 times larger than the one that came with the steering wheel. I think this one will stay on.
Thanks everyone.
