I got a 2004 ford ranger 5.0 (was 4.0) 4wd (explorer was awd) and its finally finished but im getting the code p1729 i swapped the awd transfer case with the bw4406 electric model with shift motor, idk how im getting p1729 because the explorer was a awd, im probably missing a wire on the ecu side that needs power or ground, what pin number is it
