I installed my Foire FWA and quad a few weeks ago.
Basically, get under the car and take the little cover off the bell housing and pop the cable off the fork. Then go under the dash (take the drivers seat out) and take the cable off the quadrant. I would recommend installing a new quadrant too, I changed mine because the stock on it plastic and mine broke. All you do to change the quad is pull the two cotter pins out and slide the two pieces off, then slide the new one on both metal rods you pulled the pins from, then put the spacers right, and put the pins back on.
For the FWA, there is one screw on the FW where the cable goes through, take that off and pull the cable through so its all out of the cabin. Then line up the hole that was already drilled for the screw you just removed for the stock crap ,and thread it, then line up the second hole, drill it, thread it, and repeat for al the other mounting holes.
Once you are done, cut the big rubber part off the cable and the part that goes around it, put the FWA together, then put the cable through it, hook every thing up, then set it how you want it.
