S2 horn wiring.

[MartinBrown2409]

Hi all, I have managed to get all electrics working so far on my 1990 S2 apart from the horn. Haven’t managed to look under any other S bonnet so hoping someone here can help me with wiring tips as I haven’t been able to find any info as such. Have twin horns but no wires going to one of them at all. Have a purple wire that is really stretched to connect to one horn, in this “loom” there is a black earth connected to the chassis.
From another loom I have a black wire connected to the same horn and a two purple wires going into same connector not connected to anything.
Have tried a few different combinations but not getting anywhere. It isn’t the fuse, hopefully someone has similar setup and can tell me which goes where.
Thanks

Thanks I will give that a try, I believe that the same fuse does the clock as well and that’s now working. Yes the purple wires do have a black trace. So I have twin purple and a single purple and two earths so looks like maybe the earths aren’t good enough.

Hi all, thanks for advice, complete novice when it comes to car electrics. Horn now working, poor earths.
