Tach learning problems

Not unusual on Toyota trucks. It seems that after the 10 seconds, the voltage on the tach wire drops below 1 volt, and the remote star need's 1 volt or more.The TACHOMETER is black or blue/white @ the instrument cluster, on the brown plug. But take NOTE!!It is black on the 6 cylinder models, and blue/white on the 8 cylinder models, at the instrument cluster.On the 6 cylinder models the black wire is also found on the drivers side of the motor at the diagnostic connector. On the 4.7L V8 can also use BLACK/ blue at coil #1 on the drivers side. So you might want tomove it around to get the best spot
