What are the Unichip wires supposed to hook to? My guess is ignitor tach output, map and a few others.
You should be able to just trace the wires from the appropriate sensor to the ECU. Then do a continuity check to make sure you have the correct wire. Toyota doesnt change sensor or injector wire colors from the connectors in the engine to the ECU. So, if you find them in the engine bay they will be the same color on the ECU. Most of the time toyota only uses 1 color combination on each connector.
