4agze tacho not working

[Intense]

I bought a kouki jdm guage cluster for my ae86 today. Before I had a adm guage cluster in it and I followed a PDF guide on how to get the tacho to work, and surprisingly enough it did work. All you needed to do was replace 3 parts on the circuit board and it would go.
Now knowing the new cluster is just normal I swapped the modded circuit board from my old cluster with the one in the new cluster. But it won't work.
This is the stock circuit board from the kouki cluster
Here's the guide I followed to get the old cluster working

Any ideas why this one won't work? When I turn the ignition on the tacho levels to 0 but when I start the car nothing.

if the board worked in the old cluster, it should work in the new cluster if the cluster harness pinout is the same between the two.

I put together that PDF guide and I've used it on a whole bunch of AE86 and AE71 tacho drive boards with sucess.

I'm gonna give it a shot with the kouki cluster circuit bored and swap it all back in. Fingers crossed

ok swapped the components onto the kouki circuit board and the same thing. Tacho won't work. It moves a little when u turn the ignition on but then just stays at zero.

so have you checked to make sure the harness pinout is the same between the Aus AE86 and the JDM harness. Wouldn't suprise me if you had to repin it.
