453 Horn Fault

Modification Details

453 Horn Doesn't Work

This is a new one that's appearing more regularly on the 453.
What confused me was that most people also had issues with their headlights in some way.

So, I took a long look at the terrible wiring diagrams for the 453 to see if I could find a cross over.

I was surprised at what I found. Then I realised we are dealing with Renault (French) wiring.
Then I wasn't surprised at all. Jeez, what a clusterfuck. What idiot designed it?

Initial Checks
