Dear All,

I've located fuse No.19 for the horn.
It's in the plastic fusebox on top of the battery.
Hopefully, I've uploaded a photo here:

If so, it's the only yellow 20amp fuse in the middle row.

Continuation...

I intend to fit the Denali SoundBomb Compact horn I bought from a Motorbike shop earlier today.

However, this horn requires a 30amp fuse (that's easy coz I've just found the fuse for the horn (Fuse No.19)), and it requires a 30amp relay.

Where on earth is the relay for the horn?

According to the very detailed wiring diagram kindly provided by skaramanga in their post of Sun Sep 01, 2024 11:47am
the horn relay is "located in the lower left-hand section of the battery" (see attachment below)

Continuation...

The Horn relay is on section 2700, location G

My question is, does anyone know where 2700 is?
I've had quite a scout around the battery (12V battery) and I can't see it.

If I can upgrade the fuse (easy) and upgrade the relay (location needed) then the wiring (will check with an auto-electrician) might not need to be upgraded, and the horn installation will be fairly straight forward.

Would love to know your thoughts!

Best!
