well in mdclears case i apologize, i just assumed yours was the norm, but in the diagram wich isnt very well drawn there is a positive marking at the end of the wire (+)
Horn goes off randomly...

lol so ur telling me that both the red and black wires in this picture (that i took when first installing my boss kit + steering wheel) are negative grounds?Joshy_morris said:

correct, earth the one thats not bolted down with the ignition on and i bet your horn goes off. none of those are powers.
LOL the last few posts are not making sense at all.
Im preee sure you dont have TWO earths for your horn, if that were the case I wouldn't need Energy Australia, I would just wire all my appliances to ground and run them...

the fact remains, that there is an active wire, running to your horn. It is fed from a fused ignition-switchable source and earths at the horn switch within the boss (which is grounded). The only thing wrong with the pics, is that they only show the horn coming directly off the + side of a battery, where they really have an ignition then on to the horn-boss switch. Your horn doesn't work when the ignition is off (or does it?!)

Pretty sure mine does.
OP - Just hold your horn switch on, and start connecting the wires you see in your steering wheel, earth them, short them. Its either going to turn the horn on or not. Thats wat id do.

OH MY GOD .......
can someone tell this person how a switch works? you dont have a power and an earth to your switch your fool, otherwise that would create a dead short when u press it. if you dont know how electrical circuits work then dont act like you do.....
and yes tryg is 100% correct, although alot of cars have there horn to a constant power, the lancer however does not, it is an ignition, so in terms of this diagram being for a lancer it should have ign. next to the + but being a basic diagram its still correct.
and for trondabron, please read the diagram.
OK, last try then i give up.
your horn (the thing that makes noise) has either a constant power OR ign power to it always (fused ofcourse) now since there is always a power to this horn all it needs is an earth. yes?
so when you press your horn button, it allows the horn to get its earth inside the boss kit. wich CITTA is those 2 wires in your picture. one wire is connect to earth (wich youve pointed out) and when the button is pushed 2 contacts press together allowing that earth to travel to the horn via the other wire.
now if you still dont understand what is going on, and why there is 2 wires in your steering wheel and none of them is a power, i recommend giving up and to leave the electrical work to the experts.

I never said you have a power AND a ground connected to the switch, I simply said you don't have 2 grounds. Which is what you inferred when you told Citta that his red and black wires were both earthed.
After all of this, has lmck33 got his horn working?

lol this is still going.
i did physics at school and know circuits so it finally clicked in my head wat he meant after i saw the circuit diagram lol. hes right.
even though for some stupid reason one wire is red and the other is black like in most + and - cabling, both wires are from the negative side of the circuit and all the horn button does is complete the circuit.
also tryg is right aswell. the negative wire comes off a switch on the ignition so that the horn only works when the cars on.
so in a way it has two switches really. this is what the diagram should actually look like.
diagram A. is with the car switched off and no one pressing the horn in
diagram B. is when the car is switched on and u press the horn.

lol nice pic citta, yeah, when working with wires NEVER assume colours equal anything, so many times at work ive seen home jobs where theyve used whatever wire they can to wire things up (eg trailer plugs) lol bodgy bodge.
and yeah your correct about the ignition switch too, although not every car has an ign to the horn. sometimes its a constant.
