Made some nice progress this weekend.

5 spd trans is in. Removed the auto and flex plate from the engine. Installed new 2 peice flywheel with exedy stage 2 clutch.

The only problem with using the 05 trans is the bell housing had 6 bolts (vs 4 from the 98). I took a 12mm bolt and made a 4" long stud. I then tapped the lower starter hole in the 5 spd trans with a 12mm 1.5 tap. I didn't tap all the way through the trans so my stud would have a stopping point. Then, I inserted the stud with some loctite on it into the trans. I had to drill the hole in the starter a little larger to fit over the stud, but everything is good now. Some people drill and tap the block, but I thought this was easier and since the auto is set up this way, it is proven to work.

The pedals were a PITA. You have to remove pretty much everything from under the dash. I didn't disconnect anything, but just unbolted and tied up out of the way. The new pedal box is a lot bigger then just the old brake pedal. The clutch portion of the box fits through the holes in the firewall where that black plug is next to the brake master cyl. The clutch master cyl bolts to that. replace all electrical stuff in a new home under the dash.

Manual trans went in like butter. SOO much more room under the car now. The auto is gigantic and I should be saving about 100-150 lbs from this swap as well. The bolt holes for the x member are by the control arm bracket. They had rubber plugs in them. These are a fine thread. 12x1.75. I used 30mm long bolts with a large washer on them. The two holes f or the shifter assy are also plugged up by where the shifter is. They are standard 8mm x 1.50 IIRC.

I used sedan axles. The 05 axles have exciter rings on them for the ABS. Our cars have a diff set up. These rings on the axle have to be removed. A punch and hammer makes quick work of that though. The reinsert into the car as normal.

The wiring was a little tricky. The 4 eat has 100x87597657 wires going to it. You only need 4. 2 for reverse, and 2 for neutral safety. There are also 2 wires that come off of the little switch on the shifter that allow you to get your keys out and I have heard turn on the fuel pump.

The 4 wires you need come off of the trans inhibitor switch selector harness. I used the factory pig tail tail and cut all the wires off of it except the 4 I need. This makes for a cleaner install and you can still unplug the trans from the harness. The pin numbers are 9-12 (9, 10, 11, 12) on the harness side of that plug.

9, and 10 are for the reverse lights. Plug them into the 5 spd reverse switch on the trans. It is the white switch at the back of the trans. There is a black switch on the trans as well, but we dont need it. IDK what it does. Mine must be bad because even w/ a mutimeter I couldnt get continuity out of it. I let it hang.

11 and 12 are for the Neutral Safety switch. I plugged them into the clutch pedal switch. There are 2 switches on the clutch pedal. The bottom switch is for cruise control dis engagement. You dont need to use that one. The top one is the NS switch. When you puch the clutch pedal down it closes the switch and completes the circut. Clutch is out circut is open and cruise works.

Use your old vehicle speed sensor. The newer VSS's have 3 prongs. Ours only have 2. They look diff but are a direct swap. You will have to extend the harness a bit to make it reach. Also, there is a little metal peice that goes inside of the VSS. Ensure this swaps over with the sensor. It falls out of the switch very easy.

My auto driveshaft is too short and so was the sedan 5 spd drive shaft. I am thinking I need a wagon drive shaft, or have mine extended. Ill post pics in a minute.
