[s-cars] ECU pin-out for tacho.

[Tony Guttmann]

Scott Mockery's excellent site gives the ECU pin-out for S-cars, showing
the tachometer signal given at pin 40. As I'm having trouble picking
up a tacho. signal from that pin, I'm wondering if anyone can provide
independent confirmation of that fact, or, in the unlikely event that it's
another pin, what is it?

Many thanks,
