I've been a machanic most my life. Looking to do a lightning motor in my f150 4x4 from a 2004 donor truck. What do I need to know and please don't get mad at me for asking looking for some real help.
I don't mind loosing 4x4 low it's worth the trade off for me. Please tell me more so I know what I am getting into.You will lose 4x4 low, ecu controls it. 4x4 high is controlled by the GEM module. There is a wire I moved in the harness that passes through into the cab (driver's side firewall). I don't remember what it was for, I did it 15 years ago.
