Disconnect the battery and remove the ECU from the passenger side kick-panel and remove the connectors. Pins '''101–106''' lead to the injector wires; you need to solder resistors in line on each one of these wires. The bottom connector (as the ECU sits in the car) contains pins 101–106 on the end of the connector opposite the locking tab. Notice the wires here, they are green in my harness (and most likely yours also).
