How hard would it be to convert my sd mustang to maf?

 

EASY!!!!!
3 ways to do:

1) Buy the conversion kit.
2) Rob a 1989-1992wrecked mustang for the harness and computer.
3) Buy a A9L computer with the pig tail for maf and pin it into your facotry harness.

The first two are relatively simple, the last one a little more complicatied.

 

I think #3 is fairly simple. I just ran 4 wires through the firewall grommet, spliced & pinned.

 

As far as #3 goes what wires am i splicing into on thefactory harness
