Second one goes to the IAT under the plenum

Re: Need help identifing wire harness plugs
I was thinking that cause I don't have a wire for the IAT sensor. This connector doesn't reach and is not the right connector. Is there a wire that plugs into this that connector and then plugs into the IAT??

Dyno Don is right. And no, it plugs straight into the IAT Sensor Wire color is Tan and Black

Yes, there is a pigtail that goes to the sensor and it plugs into that connector.

Re: Need help identifing wire harness plugs
Is the IAT and the MAT sensors the same? There is no way that wire reaches under the plenum and the connectors are different. The sensor I have under my plenum is the same as the coolant sensor

Re: Need help identifing wire harness plugs
Ok that would make sense. Any idea where to get that pigtail? The car was stored in a buddies garage and I think he took a few things. I think that was one of them
