Need some help f150

I have 87 f150 351 I want to convert it to efi how hard would it be to wire it

Love that year model. If you purchase a conversion kit for the 351, the wiring is quite simple. Keep in mind that it wont run the same afterwards. I converted an old Dodge and it didnt seem to have the same raw power as before, but that could just be my need to work on something. Reverted back to my Holly. Much more simple and mean.
