American Muscle says the M-12508-M50 engine wiring harness will not fit a Boss, only a GT, which makes no sense. So I called them and they assured me it would not fit a 2012 or 2013 Boss. I then asked FRPP and they said the M50 harness and the improved camshaft actuators will work on my VIN specific Boss. So my question, can anyone confirm that they have successfully installed the M50 and the improved actuators on a 2012 Boss? I would not want to spend money on new parts and the PRS upgrade only to not have it fit or work properly.
