I am reinstalling a 2001 lightning motor and I cant remember where this plug went or even if it was pluged in. If you follow the injector harness from the passenger side around the back just behind the blower. It is by itself and about 3 to 4 inches long. any help would be appreciated. Below is a link to the pic.

Link didnt work. What color and how many pins are in the connector? Could be a number of things. 02 sensor, IAC...

 

sorry about the link. Its not the O2 sensor for sure. The plug is black and its a 2 wire. If you have an email ill send you the pic. Thanks in advance

 

He already told yuh, -IAC lol. Yea, it,'s between the O2's on the harness. - 5four only I believe. You didn't post your old engine so I can't help much.

I'll guess it was a 4six, - since you don't know what the connector is for.

The 5.4L's and 4.6L's have slight differences and IAC location would be one of them. The 4six was driver side of the Plenum or body and elbow. The 5.4L's are in the back by the firewall and they favor the passenger side more than the drivers.

I don't know what else would back there ? The Knock Sensor harness threads from front to center of the engine, but ends up fairly close to the IAC.

It's gottuh be IAC as Toyz posted earlier, - because it is.

Fun project, hope you taking pics !!

 

Im not converting 4.6 to 5.4 its a lightning. and its not the IAC

 

Alrighty then.
