Aftermarket horn

[hulk311]

A while ago I installed this horn in my truck. http://www.harborfreight.com/cpi/ctaf/Displayitem.taf?itemnumber=94862

While in my brother's basement I found another set of the same horns but the relay is broken. How do I go about installing the set of horns I found to my existing horn without using two relays?


The relay has 4 wires:
-connection to existing horn on steering wheel
-30A fuse
-ground
-compressor

Is is possible to hook up both compressors to the same relay?

Is it as simple as hooking up the 2nd compressor to the same wire as the 1st compressor?

Also, should I increase the fuse?



:awais:

You can, but I would advise against it. You can use the same trigger to supply 2 relays, but I would not feed the power to both off the same relay. I have a feeling you will fry the relay in a heart beat doing that. You can get a new relay for $10 at best buy .... and probably $4-$5 at any auto parts store. Just say you need a single pole double throw (SPDT) relay ... The ones I care are made by bosch... best buy keeps ones from Directed Electronics but they are all the same.

That's awesome man. Where did you mount the compressor? That's the only thing holding me back. I don't really want to mount it under the car, due to decreased ground clearence.
