I just bought a 2012 limited. 3.5L V6... I noticed under the hood there is a wire coming from a part behind the power steering reservoir, attached to the firewall, which appears to be a ground wire, and it's not grounded to anything. I was going to just ground it to the nearest source, but I noticed that this wire is the only thing coming out of the part, whatever it is. The part number is PBT-GF30, I believe, but I cannot figure out what part it is. There are two more numbers on it, 244761191 and EP2QA. I don't know what this part does, since the car runs fine... But I want to ground this wire to wherever it should go anyway. Can someone take a look under the hood of their edge and see what this is grounded to? Any photos will really help. I will add some photos shortly.
