Wiring Up A Horn On Escort MK4
#3
I've found that life I needed.. It's HERE!!
There should be a sprung contact tail that fits to the steering column and then plugs in to the loom, 200mm long or so if you want to use the steering wheel horn push.

edit:
basicly when my old 1.3 ovh engine was in, the loom had wiring for the horn, but since I've done the conversion I havent been able to find the horn connection on the new loom that is now in there running my mfi engine, so can't I just make up a set of wires (red + black) from the steering column somehow and run it through the fuse box?

This is how I would expect the setup as per the OE setup, two permanent live connections (Via a fuse of course) to a relay, from the relay to the horn(s) the ground for the relay goes via the switch and the other side to earth.
When the switch is closed (Actuated) this completes the relays earth circuit thus closing the relay so then live power is sent via the relay to the horn(s) which have there own ground connection.

When i converted my old estate i had this same problem what i did was find out what colour wire it was for the horn wiring from the haynes manual which i think is yellow with a red stripe but im not 100% on that so best to check. I then used a sharp blade and carfully cut some of the loom tape off on the lower cross member that runs in front of the radiator, find the correct colour wire and solder/crimp a piece of cable on to reach the horn,plug it in and retape the loom up.

A few weeks ago I went to fit two new chrome horns in my car and for some reason they don't work, I then went to put my old ones back on and they don't work, I can't understand as they where working 5mins ago can any one help?

Can't 100% remember on mk4's but the mk3 definitely doesn't use a relay
Yes it gets its power from the fuse box
Such a simple system,why would you need a relay as it doent draw a lot of current
Wire colour is usually red/yellow
