New Cluster Problem.

[A1phazu1u]

So I purchased a Cluster with a tachometer(RPM Scale) because my original Cluster did not have a tach.

Then i installed the New Cluster and it works great except for the brake, tpms, and abs lights stay on. And the mileage is off.

So i read somewhere in the forums that if i were to switch the little board on the new cluster with the old one it would restore my original miles.

I did exactly that and everything seemed to work perfectly, it even turned off the tpms, abs, and brake lights.

.....But, i quickly noticed that the Tachometer wasn't working. "FML"

So, is there any solutions to this problem? Its for a sedan btw.
