There are so many threads on this, you could easily find this info using the search function.
You need the OBD1 ECU and distributor along with the OBD1 harness side distributor harness clips, and a 4 wire O2 sensor. You'll also need to either repin the distributor harness or splice the wires and solder them together. You can search for the chart on what wires go together.
