Someone please help me

What I’m really curious about now is… how did you get around all the factory electronics in this deal? Wasn’t this around the time when Ford started using the Gen module body computers to operate the gauges and power anything on their cars?
well as you said everything is all connected..so that being said I just simply unplugged the harness and poped the engine in with its own equipment, no wiring no setup just combine the red with red on the terminal lmao
