It plugs into fuel rail plug has if I remember over 20 clicks you turn it with screw diver. Haha I don't think it's like you say Tony. As big mountain to climb before my house . Stock tires small 15in it would pull 5th gear wide open. With 33s no more pull 5th gear wide open. I only set tuner to number 7 it now pulls 5th again easy in 5th gear . It's a digital tuner. I was surprised I could order it in USA.. as no np300 diesel ever sold in USA
