FIAMM air horn question (blown fuses)
I installed the dual FIAMM air horns a few weeks ago.
I replaced the front horn with the air horn and left the second horn next to the belts.
Now if I hold down the horn for more than a second the fuse blows. (10A)
Whats going on

In the box with the FIAMM horns there was(should've been) a relay - use it ! Your stock harness is not designed to handle the load.

I never opened it but I assumed it has a pump inside (and maybe a relay) Anyway it has a + and - on the bottom.
I hooked the + up to the old horn and grounded the -.
Is there another way to hook it up? If its a relay, where do I connect the power?

You can either
a) be stupid/brave and replace a horn fuse with a 20 amp one... (That's what I did) Don't later if your car catches on fire
b) be smart/trick and get an automotive relay and run a separate 20 amp fused line of the battery thrugh the relay to the horn and control the relay with a stock signal
On an ISO relay I would connect stock horn connector to "86" and ground (chasis) the "85". and then run a wire with an inline fuse(20A) from the plus of the battery to the "30"("30/51") and then run the wire from the "87"(!Not "87a") to the "+" of the horn compressor and then ground the "-" of the compressor

Use the horn + as a signal to turn on the relay and take power from the battery. Cool!
