i got my hella horns today and was wondering if you can just plug them in or do i have to use the relay that came with the horns.


anyone?

 

I thought that you used the hella relay way of wiring them up but don't quote me on that.

 

the directions say to use their diagram, but i was wondering if they are like the freeway blaster horns, so all you have to do is plug them in and thats it.

 

did you try searching? I think this has been covered before.

 

3.4,

Which Hella horns? If the Supertones, I installed them w/o the relay and I've never had a problem. Just a matter of splicing wires.

If the air horns, no clue. As the previous poster said, a search would probably answer your question.

air horns would need a relay

 

technically you wouldn't need to use the relay but you may find yourself in need of replacing a fuse...

 

your horn system actually has its own relay... i have installed air horns in several different cars and the stock system was fine

 

I installed my airhorns with the supplied relay. I figure they must have given it to me for a reason. But it also came with a horn button, which I didn't use. So you figure, that the kit can be installed on cars that never had horns. Thats prob, why it came with the relay and the horn button. But I decied to use the relay.

 

How do you install the supertones? my stock horns have one little plug thing and the hallas have two prongs

 

If they are the Freeway Blasters then you don't need a relay. One prong to power (same as stock) and the other prong to ground (the bolt that holds the horn on the body.

 

You don't need the relay if you get rid of the stock horns. Whether they are air horns or just regular horns, you use the existing wiring.

Now, you would ONLY need a relay if you wanted to keep your existing horns where they are, and add a 2nd set, for a total of 4 horns. Most don't do this.

More info on my site, look for the air horn write-up.

 

What Jason said. Plus, you can leave one of your "Roadrunner" stock horns in place on top of the new horns (as a wimpy back up).

 

alright, I'm havin' probs here.. do you just cut off that stock harness and splice those 2 wires together? and then ground the other end?

 

got one horn installed.. dont even know if its working right... so I just threw everything back together.. guess I'll wait till I get a specific answer how to do it

 

plug the wire from the stock horn onto 1 prong and just ground the other prong.

 

i think he's got two horns though. should he split the positive wire for each horn?

 

Woa! Air horns draw 20amps+.
A 14 gauge wire that loops through the steering wheel is long enough to be grossly undersized.

 

i have 2 horns also ... there will be 2 positive wires ... one for each horn, then just ground each horn

 

that first harness has 2 positives? and the second horn doesnt? hmmm
