Loose ground wire?

While trying to diagnose a possible GPR issue I found a loose wire that came from the the engine a couple of inches below the valve cover on the drivers side of the valley. The wire is black so I am guessing that it is a ground wire. Anyone know where this wire is supposed to mount? I can post photos if that would be helpful. Again, the other end leads back into the engine, in the valley, below the valve cover on the drivers side.

Thanks in advance!

be careful-could be the intake air heater wire, and grounding it would be bad-we n eed pictures.

Black can be hot.

Get a test light or volt meter, get a good ground, then hot lead to the loose wire and see if you get voltage. Try it KOEO, KOER, and any other ways you can to make sure it's hot or ground.

There should be a heavy black wire that runs from the ground side of the Intake heater to the intake bolt behind the drivers side lifting bracket.

Sorry it took me so long to get these pictures uploaded. The first pic is of the end of the wire near the GPR and the second pic is of the end of the wire mounted to the block.

Again, does anyone know where the lose end should mount?
Thanks in advance.

Look at the air intake heater it will be next to the red and green tube.
You should see the red wire on the front of the air intake heater then there will be a little insulation piece ford calls it a washer but it is more than that then the ground wire you had in your hand if there is not one there already.

It will not hurt anything if you leave it unhooked the air intake heater just will not work.

I would tape that lead up or remove it from the AIH relay if that really is what that is because it is a hot wire.

That is the ground wire for the intake air heater. Look at the IAH and it should have 2 wires going to it. It only has 1 post so you take the nut, red wire, and insulator off. The black wire goes on 1st then the insulator, red wire, and nut.

The heater should ground enough through the intake to not need that wire but I would put it back on anyway.
