MHD FlexFuel Kits use a different harness on the F Series and G Series BMWs. This harness only works on B58 or S58 powered cars with an Automatic Transmission and MHD FlexFuel Kits. Visually, the harnesses look similar, but the pinout is different, along with a connector protective Key. NOTE: Each harness is tested before shipping out. Sold harnesses can not be returned.
