What Does This Thingy plug onto????
 

https://cimg0.ibsrv.net/gimg/mustang...05a025da0d.jpgAnyone know what this plugs onto? i have a 02 mustang GT and recently had the intake manifold replaced and noticed this "plug wire was unplugged and cant find what it is for and what it plugs onto.......?

It's a ground for something, I forget what. Look on the fuel rail near cyl #8, there should be an exposed stud sticking up, it snaps right onto there.

cars driving like crap so i hope it helps after plugging back on.

i dont see this stud anywhere

I'm not very familiar with 4.6 engine wiring, but FWIW that connector reminds me of a sending unit connection, like for coolant temp or oil pressure... Is there any chance that it's not a ground? What color is the wire insulation?

Z28 is spot on and it does connect to the fuel rail stud

thanks z28\all plugged back on! :)

anyone know what that ground wire is for? im just curios now

i cant recall exactly what circuits its for, but i can tell you from experience that if your main engine to body ground strap breaks and you try to start the car that little wire will go up in flames lol

What is your oil gauge reading?
