Put engine back in, tach doesnt work

I put my 91 GST engine back in over the weekend and when I started it up the tach doesnt work. What could I have forgotten to hook back up under the hood?

Is this a different car than your profile or are you putting a '91 GST engine in your '90?
The tach signal comes from either the Tach Gate on the coil pack on a '90 of from the Power Transistor Module on a '91+

I actually have a 90 laser turbo and a 91 mitsu eclipse GST. Thank you I will follow those up.
