Im in the process of putting a zetec engine in my mk4 escort estate and im abit stuck finding the plug for the horn ive got the main loom in place, clipped in and labeled up as to what does what apart from i cant find the connector for the horn
Ive got this plug coming off the main loom






but its no where near long enough to reach the plug i need it to and theres like 5 wires going into this plug where as i only need 2 wires for the horn



so im thinking ive got abit of my loom missing but ive not got another one to look at so i aint got a clue please some body point me in the right direction of these illusive wires im looking for cheers mark.

 

ive got the same mate,come on someone must know

 

i will have a look in manule (if i can find) tomorrow, see if i can find the wiring dia for it

 

Im glad im not the only one boothy its probably really simple but ive been through the loom and there isnt another another plug apart from that yellow one

 

come on some ones got to know what im after

 

Going from my mk4 XR3i Cabriolet i had a few years ago, i remember seeing this plug both male and female, these were never plugged together when i had the car.
I thought at the time it was for the horn, but the horn was working fine without these connected together....so i connected them and nothing changed, horn still worked. i unpluged them and left them disconnected.

hope this helps.

 

Its not that plug mate, that one is for either heated screen or mirrors, cant remember which. Surely you must have a black plug dangling somewhere with the speedo wires? Must be missing surely off your loom as ive always found the horn wire sort of finds its own location!

 

It could be for the heated screen it certainly sounds feasable ive been through the hole lump of loom and there isnt another plug i think im just going to have to run a couple of new cables in and be done with it cheers any way
mark.

 

Now then mate, ad my dash out today, and basically its a black blug with a brown wire and a white wire going to it-its taped up with the stalk wires and the igniton barrel wires. If it aint with them, its gone walkies from your loom....

 

That looks like the plug for the optional fuel computer. The horn plug comes out by the ignition plug socket.

 

I'd agree with that, had my dash out last week and found that plug. The fuel computer is the only thing my car doesnt have and so its just at the back of the dash never been used.

 

Cheers guys ive been up last night and had another rumage through the loom but still nothing would i be right in saying if the looms previously had an alarm fitted would they not need to tap into the horn wireing so that it beeps when the alarm goes off crude i know but ive found remnants of an old alarm system

 

If it helps it should be a red and yellow wire

 

That wire comes from the horn relay to the horn. The plug you need is a 3-pin one with a brown/white wire and a brown wire (as the horn contact works on an earth, not a +12V) with the third pin empty.

 

Im getting some where now ive been up and unwrapped some more of the loom and ive found a brown wire and a brown with a white stripe after reading ians post i think ive found my illusive wires all be it with the plug cut off but it aint the end of the world getting the soldering iron out again
