Hey guys... I have a wolo 320-2T high/lone tone horn on my civic... I wired it through a relay but I'm having issues... I'm aware the horn has it's own relay and to that I have my alarm horn honk connect on the horn trigger.

But the aftermarket is hook up this way on a separate RELAY.. 30 to battery with 15 amp fuse. 86 to horn wire. 85 grounded to chassis and 87 to horn.

Horn has 2 terminals any side can be use as pos or neg. Horn is grounded with brace to chassis and termnal connection.. other horn terminal to 87 on relay.

My issue is with car off horn honk loud and clean even with alarm... but with ignition on and running it's low and distorted...

Is this a grounding issue or relay issue?

 

I don't know what the numbers^ mean.

Post pictures of your wiring job or post a circuit diagram.

You also need to mention what car you have.

 

The pinouts on the relay.

 

Here's a sketch Ron. The car is in my thumbnail. 98 civic

 

That helps.

What car? Are you using the original horn relay?

 

1998 civic ex. The original relay that is under the dash next to the fuse box is still there. The relay mounted near the horn is a SPDT 30 amp relay I got from autozone.

 

Do I need the second relay (not the horn one in the dash) to honk the horn and be safe?

These aftermarket horn draw 15 amps....

 

Below is the horn circuit for the stock 98 Civic. I see no need for the aftermarket relay. Just attach the Blu/Red horn wire to the aftermarket horn (+) terminal and leave aftermarket horn ground wire attached to the chassis as shown in your hand-drawn diagram. Installation should be that simple.

 

Won't the amp draw from the horn blow the fuse and also make me lose my brake light or it lighting up with horn pressed? I just wanna be on the safe side.

 

Try it. It's just a fuse.

 

Ok thank you

 

Your stock 15A fuse should be fine. Wolo's tech specs only call for a 15A fuse on the horn.
