I have an 1989 Grand Marquis 5.0 and i have a question about the wiring harness. Ive been wanted to do some mods to the engine that would require larger fuel injectors but being that the car does not make use of a mass air sensor how can i control the fuel system. Im wondering if I would get a Mustang 5.0 engine wiring harness and computer and the mass air sensor if i could just swap the marquis out and bam.

Just use a speed density-managed HO computer. Look here for all the information you could ever want on the HO conversion:
