Do you need a PCM and 5speed Harness for this?

No wiring changes are needed. The pedal assembly is a pain - plan on removing the drivers seat and dropping the steering column. Install the quadrant before you install the assembly.

you may have to cut the tack welds on your crossmember to adjust it into the correct position.

wiring - I have heard stories of people splicing and soldering for the neutral switch and reverse lights. None of this is necessary. While you are installing the pedal assembly, look around up there. the plug that goes into the neutral safety switch is there somewhere, it has a "dummy" jumper in it. take out the jumper and plug in your NSS. If I remember correctly, the same deal applies for the reverse lights. everything is plug and play - I sort of remember using the jumper i removed from the NSS vehicle plug and using it to jump 2 pins in the 4 pin vehicle PRNDL switch (jump the starting lockout circut, the other 2 pins are for reverse lights - i think the T5 plug goes right in)

pm me if u have any questions
 
You will need the harness for the five speed for the lights. It is cheap and very easy to install. Other than that everything is plug and play. I have done the switch both ways on my 92. I went to a five speed and just went back to an Auto. The pedals are a pain but other that nothing is too difficult. Good luck with the swap.
 
the pedals were a major pain in the ass on my lx 93 all th wiring is plug and play a jumper here a plug there the hole in my floor had to be cut out bigger for the shifter have fun
 
sometimes you have to trim the tranny tunnel a little bit to clear the front of the shifter assembly, the bolts hit it. had to do so on my 86. IMO an A9L computer works better with a t-5 than an A9P, which is stock in an automatic application.
