Suzuki Gladius Twin horns - a question

Relay terminal numbers; there are four in my diagram but relays with five are often found too, the fifth one will be numbered 87a, don't use that one, it's the normally closed connection - if you connect the horns to that they'll be on all the time unless you press the button, not good.
You'll note that the original horn connections go to 85 and 86. In theory 85 should be negative and 86 positive, as technically that's the DIN standard, but in this circumstance it won't matter which way round you put them.
Put the fuse in the supply wire as close as is practical to the battery - only the cabling after the fuse is protected, that before is not - so have as little of that as is feasible. For ease of connection you can take your supply wire from the battery side of the solenoid.
Depending on the horns you're using they may only have one connection: the positive. The negative being supplied through the bracket.

Hi Squid

Tks for the diagram and info. It has made it more dummy-proof for me.

One question though. The actual wire used for connecting everything. Is there a certain type or voltage maximum?

And what size fuse to be used?

Hi Riders

I've finally fitted a set of Denso twin horns. The reason for using these compared to other makes - Bosche, Hella - was the limited room between the radiator, tank and frame made it not practical to have larger ones. The Denso are slightly smaller diameter than the original horn size.

I used Sid Squids diagram as a base to go from. It was very helpful. With a metre of wire, relay and connectors it went fine.

One horn was placed in the original position. The second I attached to the radiator side bolt, (with a bracket) facing the horn inwards. The relay was attached to the frame with a small nylock strap. Keeping everything firm and in place. Finally the fuse connector was attached close to the battery, as advised by Sid Squid.

Once everything was in place and connected I turned the key and pressed the horn. Out came a much louder and stronger sound than the stock horn. Hopefully this will help riding through traffic here in the Philippines.

Thanks to the members who gave me advice. Its appreciated. Check out the sound on this very short YouTube video link below.
