Yes. In the reference section are the pinouts for obd2a ecu's. Just hardwire from the sensor to that. Your in-car harness isn't wired for the IAB's, and neither is the engine harness you are using. The jumper harness may or may not have the wires in place. Either way you will either have to hardwire strait to the ecu pin, or to the wire on the jumper harness coming from the appropriate pin.
