Don't know if anyone on here's done it but it'll probably be a lot more involved than on later Toyota vehicles with ECU controlled electronic fuelling and drive by wire throttles etc. The 80's OEM CC is a bit belt and braces and can best be described as electro-mechanical. The 80 series has a generic wiring loom with add on 'sub looms' for different kit in different markets. Assuming the wiring for CC is there, you'll need the control stalk, the servo operated throttle actuator and new throttle cables and the CC ECU.
Might be easier and cheaper to look into possible after market alternatives. JMO
