horn wiring central locking

[Jaid0gz]

Greetings.

I'm currently engaging in the activity of wiring my current central locking module up to the horn. I have the correct wire on the module I'm attempting connect. Now the problem is that I've traced the wire from the horn fuse in the engine bay. There is a larger gauge blue/white wire found here aswell as a smaller gauge red/black 2 dots. This is where it gets more complicated. At the steering wheel shroud, the same blue and white wire is found. When connected with the module it doesn't beep. I found the same red/black wire (assumed to be the same) at the interior fuse box. That doesn't work either. I attempted finding these same wires closer to the firewall grommet . They ain't there either. Next I tried tracing the white/blue two dots from the horns themselves but they were obfuscated by the split tubing and tape. (and apparently not going to the engine bay fuse box either). That makes me quite confused and at a loss. Does this mean I need to run a wire from the module to each of the white/blue horn wires for it to work?

blue/white wire is power when ignition on usually in my experience. when u push ur horn button when the ignition is on your horn will sound. your supplying the power from your centetal locking kit so you will need to splice into thehorn wires theoreticallly. i suggest you find a wiring diagram but the wires should go into the steering wheel shroud. you may only be looking at the ignition wiring

I think I've got the jist of what your trying to say?
You have a module that puts out 12V to operate the horn, and you can't get this to work? Yeah?

The horn on a ce (And every other car I've ever seen) is operated by switching the ground, not the 12V supply.
So, you will need to put in a relay to achieve that: the 12V switches the relay, the relay takes the horn to ground.

If you remove your steering wheel you will soon figure it out (I'd hope ?)

Spot on, find out wether the alarm output is power or ground.
If its power then do the above ^ (relay) to make that power output switch an earth output to your horn
