No tach after dohc motor swap

[conjay187]

I have a 1990 240sx that i just swapped motors out of a 1993 dohc and the car runs mint but my tach is the only thing that doesnt work, any one know why or how to fix it?

serious? you completed the swap without knowing the tach signal is different? on the tech pages there is a "how to convert your sohc tach to read dohc signal". Try that, or get a dohc cluster and swap the whole thing. Boom roasted.
