Hi,
I´m looking for a "RPM transducer / Speed switch" (# 5 on the picture below) to a MFI car.

Bosch # 0 333 400 01
Porsche # 901 615 111 00

Thanks,
// Dennis

I use these instead. Easier to find, more accurate and adjustable. You will need a relay to reverse the output as well.

Also gives you a handy RPM readout in the engine bay.

If you have a broken one, I have fixed these in the past for DDKers.
Cheers
