You shouldn't have chopped any wires to remove the MAF itself.. you need the wiring harness that you just wrecked in that car.
But im pretty sure thats all you need... mass air unit+sensor + computer + harness.
BTW. You don't *need* the bracket that holds the MAF down, many people here on stangnet including myself have the "floating maf" without the bracket, no troubles with that.
