you have the gray, purple & black wires you need right there in the control box. if you have the factory controls, there's a 3-pin socket covered by a rubber boot just under the throttle tension control, it accepts a ready-made tachometer wiring harness.

As indicated, the terminal block is on the engine; you definitely have one of those.

Regardless, if you have a large red plug on your harness, the gray wire is pre-wired in your harness and available.

The '85 control units had a three conductor plug as shown below. You can buy a mating three wire harness with wire to terminate at the tachometer.
