The EGR computer controls the tach and replaces the old tach amp. It sends out the same signal.

I think if you do this you’ll also need a tach from an 82-83 turbodiesel with two pins rather than three.

Number of pins makes no difference to anything. The third pin is just a +12v circuit.
Its as simple as plugging in a tach amp to the socket and running wires to the tach.
