    *The PA sensor converts atmospheric pressure into electrical signals and inputs the ECU.

    *The TW sensor is a temperature dependent resistor (thermistor). The resistance of the thermistor decreases as the coolant temperature increases.

    *Intake air temperature sensor (TA) input
    These are some pinouts i used when i did a swap into my CRX not an H22 but i looked this stuff up before i made my mind up on which swap. If not you will have better luck if you look up (pinout) and the year and make of vehicle. The best way to make a harness is to send the harnesses from the car and the swap to rywire or other similar company and they will make it for you. Cost to time ratio I found is well worth the money not to mention it can make diagnostics easy later down the road. Hope this helps good luck. OH, You can also visit the rywire site and find what diagrams are needed.

    hey if you want the diagrams on a hard copy, i got mine from wiring-diagrams.com. you pay like 12 bucks, but you get about 25 pages of color coded diagrams for the whole car.

    lol, its not just the engine wiring but the entire car. its also broken down into sub systems. Like the starting circuit, Heat/air circuit, etc.
