needing help with factory tach
 

Do anyone know how or if I can put the factory tach back into operation. I have a 91 lx that I have taken the eng out and installed a 351W carb. Crane ignition box and light along with a few other things these are the only electrical parts. The computer and it wiring have all been taken out. thank you for any help that you can offer.

it is the computer that controls the tach
You may be able to hook it up to your crane box somehow but you would be better off with an aftermarket unit

thank you i did not know that the computer ran the factory tach. i do plan on buying a aftermarket tach.
