tachometer wire colour?

[hermanio]

my tacho shows 1/5 to much rpm. what could cause this problem ? (4cylinder swapped for 5 cylinder turbo with s2 tacho)

That must be MAC05 ECU then... I dont know if the tacho from a 7A engined coupe is compatible with rpm signal from that ecu...

Checked the wiring and it is definitely black/violet wire from pin 7 on KG ECU for rpm.

already tried that, but it didn`t work. maybe the violet-black isn`t right wire from KG ECU?

When rpm signal gets to cluster it is a green/blue wire - look for it on pin 22 of the YELLOW 26-pin plug in the cluster

purple - black comes from KG`s ECU, but what color wire in panel is for tacho?
