When looking for information about doing a transmission swap, there was some questions that i could not get answers to. My goal was to have a full working swap that was CEL free, and had the look and feel of a factory car. Here is how I did it.
Here is my basic parts list using all stock parts
Manual brake pedal
Manual drive shaft
Rear engine “transmission” mount
Stock Shift knob
Manual Steering Wheel
New pressure plate & clutch disk
Uninstalling the automatic transmission, I followed this basic information from All Data.

The Automatic transmission tunnel is about 1 inch lower than the manual tunnel, so to make clearance for the manual transmission this is how I changed the tunnel.
Got a used manual tunnel for free, traced where I wanted to make my cuts

CLUTCH MASTER CYLINDER INSTALLATION
I trace a outline of the area cut out on the firewall on a piece of card stock, I just use junk mail, then center the clutch master cylinder on it to make a template.

then cut, and paint the raw metal

CLUTCH PEDAL ASSEMBLY
A manual clutch and brake pedal assembly is required for a swap, at the time I could not find a used set for a reasonable price so I bought the parts new from amayama trading. Here is how to assemble.

I know there is a clutch pedal thread here on the forum, but it is mostly incomplete, so here is a little more info

The removal of the automatic transmission gives you around 10 CEL all transmission related. I picked up M/T ECU which does plug straight in “02+”, but I required reseeding since I did not get a master key. The dealership reseeded the ecu to my keys. 1 hour $130. This ultimately did not rid the CEL, 1 code for speed signal remained. Speed signal works as the following shows.
A/T ----------> ECU.
Trac ----------> Combo meter
M/T ----------> Combo meter
Combo Meter ----------> ECU
A converted car will work like this
Trac------------> Combo Meter
Combo Meter -------> ECU
So now we know we need to get the speed signal from the combo meter to the ECU here is how to do it.
ECU speed signal. Insert pin in combo meter harness A13 wire to ECU connector B11.

So now we have speed our CEL taken care of, lets do the neutral safety switch, and reverse light. This is the old connector from the automatic transmission that we need to use some wiring from. The actual numbers are on the connector.
post a picture
Reverse light. So from the old A/T wiring, take #2 and #3 And wire into new harness Part number 90980-11142. Then simply plug into reverse light plug on the transmission.*
NEUTRAL SAFETY SWITCH
Neutral safety switch. Reroute wire #6
to the the clutch pedal. connect wire 6 & 9 to Neutral safety switch. Part number 90980-10825
Cruise control clutch switch. Cut B13 from ecu and wire to cruise control clutch switch, then to driver side fuse box harness 1A pin 4. Part number 90980-10906.

Used wire protective wrap for wires from ecu and NSS. There is a nipple on the main grommet on firewall, i cut the tip off to feed my wires through.

Didn't want to make holes in ecu box, turns out there is one already by front right corner.

TRACTION AND SNOW.
the pwr/snow button as you know is part of the auto shift assembly, on stock manual it is a two part trac off/snow under the radio and next to heated seats if your is so equipped. luckily most of the wiring is already where you need it. there is one wire you need to extend and that is the black and yellow wire that goes to your old pwr/snow button.
your stock wiring, as you compare to the next photo, you can clearly see only one wire needed black yellow.

this photo is courtesy of solidsnake. you can see that the wiring is not in the same order as the traction only button, so make sure your order is right. Also you may note that you need a 6 pin plug versus the 4 pin plug, i dont have the part number yet but will update when i do.
there was some speculation that the old pwr/snow button will work in for the trac/snow button. It does to a point, there will need to be some trimming of your "bezel" to make it work, and also i noticed you need to pushing the button is differnt, it doesnt click out the same. it would be best to just source a traction/snow button. but here is mine temporarily.
***Update, i never put these two pieces of the puzzle together, you know how the the pwr button has a memory for the automatics, so once you turn your trac to a pwr button every time you start your car it will automatically have traction turned off! i will now keep it in instead of replacing it!******
Update 11/08/12 this is probably going to be my last update mainly because there was only one real missing piece to the puzzle. Some questioned the legality of changing the transmission and being able to pass smog here in California with there strict laws. Well my registration renewal was finally due with a updated smog check. took it in and passed without a problem. It even notes that it is a manual transmission on the print out.
