Wondering if anyone knows how hard it is to turn manual locks and windows into power locks and windows.

I've already looked at getting the motors, actuators, new door panels, arm rests and switches.

Do these parts (especially motors and actuators) fit in the original doors or should I look at getting doors that already have these parts mounted in them?

And will I have to wire right from the dash or did Ford prewire all of the Mustangs for that year?

Oh ya...I'm talkng about my 1990 LX 5.0 hatchback.

Any help would be cool
