After looking for a while why the spitfire switch did not work i found this great page from a vitesse
https://vitessesteve.co.uk/LucasStuff/Triumph-2-speed-wiper-wiring.htm
and decided to try it on my spitfire custom wiring:
Earth check
+12 V to slow (5) --> wiper motor slow speed
+12v to hi (3) --> wiper motor fast speed
it works, now test the wiring with the park setting
It works. Now where did in put my windscreen wipers?
