Tacho doesn't work

[tomasS]

Hey chaps I've got a 4agze in my ae86 just wondering where the tacho signal comes from cheer
ps it has a cas not dizzy

Tacho signal comes from the ECU. You need a tacho converter (or a couple of diodes off your coils) to get the stock dash to work.

Google it. It's all on here or Toymods.

Sorry. I think I might have lead you astray. Factory ECUs may not have a tacho out signal (someone can confirm/deny that).

In any case, the following should work:
