INTRO: One of my Wii remotes kept on moving randomly in one direction which had the Wii Motion Plus. With the nun-chuck installed, If I pushed the connection joint to one direction it would work but as soon as I let go, it would move by itself. I had to remove the Wii motion plus in order to use the Wii remote.
So I took it apart and noticed that one of the wires from the ribbon cable (to the solder connection point) was broken. It's to be expected since the wire is very thin and flimsy.
** "Y" Screw driver tip (almost like a Philips screw driver but missing one side AKA Triwing/Trigram).
**Soldering Iron (Moderate soldering skills required, novice dare not try) I recommend TQ-95 Click Here $34.95. or cheaper one will work too Click Here $5.65 shipped.
**Solder Click Here $1.74 Shipped.
**24AWG wire (Any color) you can substitute for any size smaller but smaller is brittle and may brake again! I wouldn't go any smaller than 30AWG. Stranded not Solid core but solid core can be used if no other is available. If anyone knows of an affordable place to get 24 AWG wire let me know & I will post.
** De-soldering pump/Solder sucker/ Wick (Optional will make installation easier) I recommend this one Click Here $3.09 Shipped.
**Flux (optional but mandatory if you damage the board) Click Here $2.06 Shipped.
You'll need to take 2 screws off and take apart the device to unsolder the ribbon cable and replace it with new wire.

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Taking the Wii Motion Plus Apart.
Photo1: Remove the screws
Photo2: Screws removed
Photo3: Remove cover (Exactly the way it shows in the picture!)
Photo4: Pinch the two white plastic clips together and pry the PCB out from it’s grip.
Photo5: Pull PCB away (As shown in the photo)
Photo6: Use something skinny to pull the plastic frame out, enough to allow your fingers to grasp the plastic frame.
Photo7: Pull out slowly (you will feel some resistance) just wiggle it out.
Photo8: Pry open the plastic holding PCB and connector in place.
Photo9: Example of PCB connector pried open.
Photo10: Plastic Frame removed from its place.
Photo11: Finally the main parts are taken out.
Step 2: Prepping Wires for Installation
Photo1: Acquire 24AWG wire to cut to the same length (doesn’t have to be exact) as the original ribbon cable.
The older IDE cables (I think are 24 AWG) could be used.
Photo2: Cut, strip and tin the ends. Verify that they fit into the holes of the PCB's (that is if you already used the Desoldering pump to remove the solder.)
Step 3: Soldering Wires in Place (Not for Novice Solderer)
On a scale of 1-10 I consider myself an 8 at soldering. But for this case I got sloppy and didn't take my time and ended up damaging two Vias (solder holes). So be careful!
Use the Desoldering Pump to remove the excess solder from the Vias.
Use flux where needed.
Step 4: Assembling Back Together
Just follow the instruction on the photos in order.
