"Supposedly" M&H wire harnesses are only suppose to be sold by Year One. So it makes me wonder who and what kind of a harness other vendors sells. Nothing against any of them because like many here, have purchased many parts from vendors. I do think M&H gets behind when Year One has any kind of substantial discount offered. I for one took advantage of their 30% off one time to purchase all available harnesses(my car) for the simple fact that I stated above.
