Does anyone know the part # of the wiring harness that connects into the steering rack? There are two sensor connections on the rack and supposedly I need a new wiring harness. I have the service advance track and hill descent control fault warning lights lit up. They come on intermittenly. I suspected the rack might be back as the sensors are on the rack that would cause these two warning lights but according to the dealership where I took it they say it needs a new wiring harness. Thanks for any help that you can provide.

Although, those lights come on with almost anything happening. Do you have other steering symptoms?

 

Well, since you didn't provide any info on your truck, I can only guess. But I believe it is going to be BL3Z-3F720-A. It appears that part number covers all 12th gens. You should really call the dealer, give them your vin and confirm before buying it.

 

My truck is a 2014 XLT 3.5L ecoboost , 4x4, super crew.
I'm also getting a grinding sound from the front when I turn left or right. I thought that this was due to my IWE 4 wheel drive hubs not disengaging/engaging properly as the sound. I replaced the front wheel bearings and the hubs but the noise did not go away so I suspected something was wrong with the steering axle since the sensors for the service advance track and hill descent control fault were supposed to be on the steering rack. My truck is currently at the dealership as I was having them look into my rear defroster not working and I asked them to check the front grinding noise to see what they thought it was. I was told the grinding was from the tires rubbing the inside of the fender wells, which I'm not sure that I believe as they are the same size tire as I had and there is no lift or other changes so I don't know if I trust that diagnosis until I can get the truck back and verify it myself. I was told the service advance track and hill descent problem was the wiring harness that connects to the steering rack. If this is a doable DIY job I would prefer to do it myself and not pay the dealership.
