Clutch Switch

As the MX5 ECU needs a clutch switch I had to find a way to add one.
The OEM switch is an electrical one driven directly by he clutch pedal.  Because the pedals in the roadster are 'upside down', the only way I could realistically use the OEM switch would be to have it bolting into the floor from underneath the car.
As that would last the length of the trip to my first speed bump I needed a different approach...
So I decided to use the same pressure switch I used for the brakes and stick it the clutch line using another 3-way T-piece:

As an added bonus it put my flexi-line to the clutch slave in a better place.
There is some debate as to whether there will be enough pressure in the line to switch it, but time will tell!
