I am looking to prank a friend of mine, we want to hotwire his horn to his brake lights or turn signals. I read about this on pirate, where I got the idea. I know that I have to take a wire and connect a lead from the horn realy to a lead on the brake light or turn signal relay. Would i connect a + to a - or what? Yes i know this is immature and stupid, but he has had this coming to him. Any tips appreciated

If you really, really, want to be an asshole, wire his headlights to his horn.:reddevil: If you are lucky, he will be forced to drive for half an hour with it screaming in his ears.

I'd just disconnect the horn, and jump the positive from whatever accessory you wish right to it, then ground on the other side. Just make sure it's not an expensive accessory, and that the extra load won't cause any problems.

But note that such pranks can possibly cause an accident.

Cheers,

Kennith

I will admit, though, that despite the dangers involved (which are considerable, mind you), this is perhaps the funniest prank I have ever seen, right up there with the train horn blowing into the shopping mall. There are videos out there somewhere.

Cheers,

Yeah, in the atlanta area him slowing down (hitting his brakes) beacuse someone cuts him off might get him shot for laying on his horn.
Fucking with someone's car as a "prank" in such a way that it could impact their driving/safety or damage the vehicle is really really stupid and the sign of a small mind. Just rig it so it burts into flames when he starts it, I'm sure that would be funny too.

Years ago we used to make a special run to Maine to get the gadgets that you wired to a guys spark plugs.......when he hit the switch this thing would began to shreik and then go off with a loud bang and it produced tons of white smoke

We quit doin that when we grew up :)

My brother has a BMW X5, and I wired in one of those $30 electric "OOOGAHHH" horns to his brake light once. He's one of those guys who washes his car every other day, notices every scratch, etc.. Man he was pissed!! It was hilarious... he was sooo mad that people were laughing at his beamer. :)

Btw - I wired the horn via a relay...

One risks getting his ass kicked for merely putting a ProComp or DAP sticker on Dan's truck.

don't hardwire anythign to someones vehicle.

put a gay pride sticker on it.

my cousing told/showed me what his buddy did in return to the sticker. haha. while out of town his buddy came over in the middle of the night and removed his rear diff cover on his F350?. he took to a shop in the morning and had it powder coated pink and the to a painter and had it stenciled with "i like boys". then the next night went back and replaced the diff cover. upon finally returning from his trip, he didn't notice the "new" diff cover for weeks.

you could also place a wrapped piece of meat, even a small one, or fish, in a very inconspicuous spot. after a few weeks, it begin to smell so bad. just be sure its wrapped. one good cleaning will get the odors out, but if it spills or whatever, that would suck.

I've got an even better one.

"Borrow" your friends car, then go drive by yourself in a California freeway HOV lane. When you get pulled over, claim you have no ID and hassle the cop (basically act like a total moron) all the while pretending to be your friend.

Oh man.
He'll be so fucked.

Don't forget to run every red light that has a ticket camera on the way to the freeway and double park a few places too...

Then he'll be so pissed that he'll pull a prank on you.. Some thing like cutting your brake lines, unbolting the driveshaft bolts till they're just finger tight, draining your t-case and diff fluid and then filling them up with water..

Really, man, leave the truck alone.. Messing with someones stuff like that is just uncool..
