Can anyone tell me what this electrical plug is for? Something tells me that it isn't suppose to be unplugged and it looks like it's been unhooked from day 1.
btw ... It's a 2001 4.0 SOHC

 

is that going into the throttle body or the sensor at the airbox? its hard to tell

 

The wires are running back towards the throttle body. It's weird, because it's just sticking out there like some kind of diagnostic port.
Could it possibly hook into Idle control unit? becuase the truck idles pretty bad right now.

 

From the picture, it doesn't even look like it plugs into anything. Looks to be wires coming off the end and going backwards. LOL Weird.

 

It's actually bolted to that big tube going to the air box.
Could it be the Mass Air Flow Sensor?

 

I think its the throttle position sensor.

 

That sounds right, but what does it plug into? (The other end of the TPS?)
Does anyone have any close up pics of their 4.0 SOHC?

 

Here's some better pictures of it

 

thats your throttle position sensor.. and it looks plugged in to me

 

Ok, I can see that it's plugged in now, but the wires are all running in the oppisite direction and it really got all frayed up. It also looks like it was rigged up with some electrical tape.
Does someone have a picture of one that's not messed up?

 

The one on my daughters Sport Trac is taped like that also.
