i had mine replaced but they did not do the MAF harness. everything else but that. my o2 sensors look to be new also. the wires on them are really clean and i know i have a super clean car but i know what new wires look like. i hate taking my car to the dealer. i asked them if they could just give me the harness so i could do it myself b/c i didn't trust them touching my car. they said that they had to do it b/c it is warrenty work. i hate ford. i really do.
