My sister in law filled my old Buick with easter basket grass on my wedding day. Never got all that out, either.

Yeah buddy, that's what we were talking about. I've got spare relays and time! Maybe we'll even add the rear wiper to that one and have it be like a sensory overload situation.

you would only need to tap into the existing circuits, you wouldn't need to "cut" or interrupt the circuit, so a scotch-lock (crimp-splice connector) into them would be all you need to pull the power and put it to the trigger pole on the relay, that way you won't risk hurting anything on your buddy's truck.

on one relay on the battery post you would put a constant power, the output post would then go to the "battery" post of the next relay, and the output post of that relay would go to the horn. the trigger posts of each relay would then go to each of the wires that you tapped into

make sense?

if you wanted to use a more complex relay like the ones used on the start interlock circuit of a motorcycle, it could be done with a single relay. but i was telling you how to do it with the common 4-post relays.

also be mindful of if the switched power of your 4-lo indicator, and reverse is positive or negative, on some vehicles they switch to ground, if so you would need to wire relay differently

Yup, we used the quick splice connectors for the last prank. I hate them for most stuff but they're perfect for pranks.

i saw that. two of my buddies that help me mess with it are mechanics (real ones) so we can figure it out. if we mess up and blow some fuses, oh well. that's what he gets for leaving his jeep at my house :rofl:

i've done the "fill car up with leaves" before. buddy left his sunroof open at his GF so we got a few bags from around the nieghbor hood.

also, moved a parked neon down the road. it was a manual and tires were point straight ahead so we pushed it 40 yards down the and went out.

Back in high school we caught a couple stray cats and put them in my friends car. He was very confused to come out to his car only to find 2 cats fighting in the back seat.

I like to slap a couple sticky wheel weights to the driveshaft. Creates a horrible vibration

One of my highschool girlfriends (not a car person) though it'd be funny to prank my car. So she smeared crisco and bannanas all over my car, and filled the car up with rice. Let's just say that I wasn't laughing when I found it. The crisco never came off, and I never got all the rice out of it.

I had a something simular I had a 1987 528e and she filled it up with popcorn to the windows, rest with ballons, and then wrapped it with surane wrap. It had popcorn in it to the day we sold it.

Buddy drove an old VW bug and we took a spray bottle and hooked it up to windshield squirters. We turned them to the the passenger's side and whenever someone would pull up next to us, we would squirt their windshield - they would have no idea where it was coming from...

My brother replaced a friends coil to distributor wire with a piece of small black plastic garden drip hose with plug caps on each end. He was sure it wouldn't run but it did, just not very well. The old auto bombs we used to be able to buy in the 70s were a lot of fun.

Had some buddies in high school that peed in the washer fluid tank of another buddies car. Then used the shoe polish stuff to write all on his windshield. So when he came out at school he used the washer fluid to try an clean it off an since that wasn't working very well, he decided to use his hands to help scrub with the washer fluid.....

My friends dad says in the late 60s early 70s they would weave a wire into the seat cover. Then to a hidden switch and then attach it to one of the spark plug wires. Then go looking for hitchhiking hippies very common in those days. These guys were Vietnam Vets so they did not think much of hippies. After picking them up and acting all friendly they would flip the switch and watch them squirm and jump he said they never wanted to ride very far for some reason. This would be a very bad on todays high energy ignition cars maybe fatal the cars back then had very weak spark of course compared to what they do now. So please dont hurt anyone with this one. Just a good story.

A friend of mine with a jeep had an uncle with an early bronco. Did you know that a precisely made "Broncos Rule" sticker fits on the lens of a stock TJ third brake light? That happened many times.

Another one was a clear license plate cover with a snapshot from an alternative lifestyle magazine inside, or whatever you feel like doing. Virtually guarenteed to get pulled over since it'll obstruct the regular plate, and depending on what you put in there, the officer may or may not be sympathetic.

on the really cold nights, get a few gallons of water and pour them on all the door jams.
baby powder/glitter in the heater vents.
horn wired to the brake lights as mentioned before.
hide a rotting fish or something similar somewhere.

Not a car prank but a good prank. Before my wife and I got married, I helped her get my best friends truck, saran wrap the whole truck with something on it, can't remember what she put on it. So my friend thought it was just her so what he did was get a 50 gallon garbage can and filled it with water and propped it against her front door. I can't remember who opened the door but when they did, 50 gallons of water got all over their floor, which was in an apartment so it was all carpet and they lived in the bottom unit which was 4 feet below the ground level so it didn't escape anywhere. ruined the carpet and some other stuff, her parents were not happy about it, they paid for new carpet I believe. Good prank though that started out by a vehicle prank.
