I think it would be safer to use a single relay.

That way you only have to add a tap to the current horn wiring for the 86 on the relay, power from the battery to the 30, ground the 85 to the frame, or battery, and 87 to the horns.

 

I was totally thinking old caddy horns. I used to have a caddy hearse... Where hearseman comes from... It was a '74. I'm going junk yard hunting or eBaying for sure now!

 

best part is they can be had for $60-$80 average... which is cheaper than anything out there that's worth buying...

 

hi,
I just mounted a new horn in my 2006 H3 , a stebel nautilus compact chrome.
it looks great through the grill and sounds good.

unfortunately the fuse has blown now. on the instructions it mentions a 20A fuse instead of the standard 10A fuse.
Can i put in a 20A without any problems?

thanks
Joost

 

'Over Fusing' the wire capacity is what causes fires! Install a relay!

 

i am not that technical so will have to drop off at car electrician.
but...does the 'standard H3 horn wiring' have not already a relay in it ?

Yes it does.....but with a 10 amp capability. You're stepping up to a 20 amp. A relay is very simple to install. You've already got the trip wire there (the wire that goes to your factory horn). Google it.

 

thanks Dr.
i am not really planning to wake up the neighborhood, or drive around the village when our team has won a match, so i might give it a go with the 15A fuse before removing the bars and grills again..

Just remember, it takes a village to raise a child and a horn to raise a village.
