I'm fitting my new twin horns today, they are normal car horns, high and low, I need to know if the horn is on a relay and if so which is positive and which in negative..

There is a yellow wire and blue wire..

The standard horn is not on a relay... not sure which is positive though.

Connect each wire to an earth with a bit of wire and a bulb, then press the horn

If its the positive one the bulb will light up

Haha thanks mate will give that a go, got one of the horns wired up for now, will sort a relay out for them later..

No relay needed juat wire it up as normal I didnt check it like twiss said. I think mine worked either way...

Have you got two horns though Tom?

I think some horns earth through the mount and the standard one has + and -
My replacement horn earths through the mount for sure

What age is yours as the early diagram shows a yellow and a blue.
The yellow is the positive
The blue is the switched earth

I only have one horn but I wouldnt of thought having to would make a difference

not sure how much power the horns take, dont want to blow my horn button or something daft..

how would i go about liking them to a relay?

ive found that most of the zuks electericals are negative switched and have found it to be a bit of a pain to wire in things like my spot lights to the main beam..

Use a suitable size wire from the battery fused to the relay and the same wire from the relay to the horns.
Hopefully the horns came with a diagram saying what size cable and fuse are required depending on there design current draw.
