I have a 1992 Ford F-150 that I just finished replacing the head gaskets on. There is a 2-pin connector by the power steering pump that I cannot place. The end of it is clean as if it was plugged in previously, because the outside is covered in grease and oil. It comes off the huge mass of wires that goes to all of the injectors. It comes off about half-way from the computer to the engine. I will answer whatever questions I can so that I can get my truck back in precise condition again.
