I got my hands on one of the Motorsport conversions for mass air. It only came with the piggyback chip that plugs into the ecu and the clip that plugs into the pigtail. I looked online an it looks like the kit comes with a harness that runs to the maf. I got it for free so I can't complain that it's missing a part, but can anyone give me a heads up as to which wires go to where so I can run them myself using a maf clip out of the junkyard? Like I said, the clip is there for the FMS harness, but no wires run into it. Thanks
