Install Aftermarket Horn

[KEVtec]

I was trying to replace my stock horn on my LX and I need some help on how can I wire an aftermarket horn (not honda brand)?

You should be able to cut and splice the wires to make it work. You might need to ground it to the car also.

the stock has only a single wire.. is that the positive? and the negative/ground is the bracket screwed to the car?

one wire goes to the ground on the car and the other is t the one from the factory horn.

here is the stock horn with a single terminal.. positive I assume and it does not have a negative terminal.



this is the horn I am trying to install and it has two terminals.. does not say which is positive and negative though.

So the stock horn uses the chassis as the ground which is connected through its bracket right?

Yea it is grounded out to the car.

Our ground is the bracket

and yes..the bracket when screwed to the frame of car is acting as a ground.

Ok got it. Thanks.

Am I good to install a pair of horns?

You could install as many as you want,just use the same power wire and grounds.

I had installed my new horns in the stock location and I was thinking to relocate the other one on the right side of the bumper to balance the bing bing sound.. :smile:

Anyone knows what type and where can I get the stock horn screws?

Here's what you need to order:

1) Passenger-side horn bracket, P/N 38151-SNA-000, $5.97
2) Bolts for horn bracket, P/N 90150-S84-003, $0.51 (NOTE: you'll need 2 of these bolts to mount the bracket to the bumper, one of which also mounts the 2nd horn to the bracket/bumper)

Be careful, though. The horns and brake lampss share the same 15A fuse. The stock brake lamps use 5.25A, which leaves you with about 9A (w/ a bit of headroom) to cover ALL added horns. So, if you add 2 horns, they must be rated at less than 4.5A each. If you add 3 horns, they must be rated at less than 3A each, etc.

I know the stock horn doesn't sound too loud when you hit it, but when the alarm system goes off that s*** is pretty loud! So if we upgrade the horn to a louder one it should make the alarm even louder, correct?

I have ordered and installed those parts already last week. No problems so far with the stock fuse.
