I did a search already and cant really find the full facts of what i am looking for -

I am currently performing a single turbo conversion in my FD ...and i will be going Haltech.
However, the Haltech does not control the electrical OMP to my findings. i will need a mechanical OMP from a 2nd gen. Or is there another way i can do this keeping the stock OMP ??
Question is how exactly do i perform this mod..does anybody have a link to a step by step or at least an article on how do i do this ??
i wnat the easiest and safest route

Thanks guys.
