i have a 94 fiesta si which i want to stick a 1.6 cvh turbo in ( dont want to do the usual 2.0 conversion)

the plan is to buy a crash damaged rs turbo and convert the lot (as need steering rack ect to as well, mines power steering,

my qustion is, does the engine bay loom unplug from the main loom on a fiesta rs turbo? or will i have to fit the enire frst loom to my si and lose the pats system ect?

has any body else done this coversion?
