Replacing the pig tail connector on the mass air flow sensor. The new one from the auto parts store has 5 wires but they aren't the same color. I wasn't the one that took it apart. I need to know which wire goes where. Thank you

Here is the connector break down for this sensor. It is actually the MAF and IAT in one sensor.

Let me know if you need more info. If you are having issues still, get pictures of both connectors (old and new pigtail). Thanks.

Thank you. he had it wired wrong. Being color blind one should never attempt electrical work on anything. Your help is always appreciated.

Haha. Yeah. That would definitely make it hard if you can't see the color.

Thanks for the update. Please come back in the future if you need more help.
