Now I'm not the electrical guru, I hooked up some autozone air horns up to the factory harness, now the compressor just seems like it needs more power. As you all know the factory wire is cheap and I'd rather not re wire the whole thing, what are your views on wiring in some capacitors? Would it work well?

 

You could run a relay so that it draws power directly from the battery instead of thru wherever the stock horn wires go through.

Id have to think a while on how to wire that up though. I may be wrong too. Something lime using the positive that goes to it as the switch on the relay?

 

Just to let you know though I've had similar cheap air horns like that. They blow... not so hard. Not loud enough.

 

So your taking the power feed from the horn wires? Use a relay and feed the compressor directly from the battery. Use the factory wire as the activation.

 

I gotchya yeah I'm not sure if they just are poop are aren't pulling enough power

 

It's been a few years since I bought one of those sets but I remember them coming with a relay in the kit.

 

Yeah but I didn't wire it seperately I used all of the factory wire how would I do that?

 

The relay should have a diagram on it, or it will be in the instructions. One pin is ground, one pin is positive, one pin goes to the compressor, one pin goes to the positive from the existing horn.

 

 

Use the relay and correct wire gauge it asks for and you shouldn't have an issue. It's almost like running a set of aftermarket fogs.
