I wired in a replacement tow bar socket the other night and found that my brake lights weren't working, turns out after testing that both brake pressure switches on the maaster clylinder had failed - I'd only tested the lights last week when I finished my Tdi conversion because I'd had the rear loom out and they worked then
Anyway, I needed them back on asap, but I didn't have any spare pressure switches lying around so had to come up with something else
Found I had a brake pedal switch from an Ford Escort, knocked up a simple braket to hold it in the off position whilst the pedal is up and making sure it clears the steering column, used part of a spare bit of brake switch loom off a scrap van that plugs it the exsiting pressure swith connector and got them working again
sorry I didn't take that many pictures
bracket with switch holder
Wiring loom with VW end removed and Ford connector end fitted
Switched fitted and loom cloth taped wrapped
All back together
and, it works great!
