[quote=old willy;1527059]Hey there,
Well I will add my 2 cents here as others will I am sure.
The button on the old VW type turn switch was used to activate a hi /low switching relay in a VW same as a lot of new cars. So if you want to go that route it should be easy to find a relay.
However I believe in the Cobra it is used as the horn switch and the foot operated hi /low headlight switch is mounted on a bracket to the left of the clutch pedal also how it was done in many older cars.
As for the heater valve it is a manually operated tap / valve on the intake manifold where the heater hose attaches and the switch on the dash really only does control the fan.
I am building an early 289 style roadster and have been sourcing most of my Lucas style knobs and switches from moss motors.
The latter 289s had off the shelf 60's Ford stuff and then the 427's went back to the British stuff. So if you want it "correct" Moss motors might be the answer for you too.
Just my 2 cents
FANTASTIC, that's a couple of dollars worth not just 2 cents
Sorts out allot of my queries. Of course the footwell switch!! I had this in my own first car however had no idea the Cobra's used these.
For the Mk III Roadster however I know the horn was a push button on the dash so I think the earth switch on the stalk could be used to trigger an on/off relay for the HB as suggested earlier. Would be great to have this confirmed by a Mk III owner.
If above is correct then the only question left is did the Cobra Mk III also have a 'HB Flash' button or do they simply toggle the HB on/off using the stalk button for flashing?
One final point, did the Mk III Roadster's have a handbrake warning light?
Thanks again Old Willy !
