If you have purchased your Wii around this time, you probably are going to have a hard time install any mod chip. Due to the fact that they may cut the pins and make it harder to modify the system. Anyway, here is quick way to install DC2key or DC2pro to your Wii by using a PCB as special aid, so you don’t need to sold with wires. it pretty much save you a lot of time. Oh for my disclaimer before you read on.. this is for private use OR educational purpose only, and I don’t take any response if you break the console or for other uses.
First of all you need some solder tools as following.
1. The Rosin core solder 0.032 and 0.022″ diameter from radio shack.
2. The 15 watts solder iron. I don’t recommend higher watts, because the heat is going to burn the board.
3. The Tri-wing screwdriver, you will need this special screwdriver to open the chassis, You can buy this from eBay.
4. The chip and the PCB.
That is it, all you have to do now is sold the mod chip with the PCB, and then place it properly with the d2c chip. Now you need to sold carefully with d2c chip as the pictures below, if you are not comfortable with soldering, you should ask the expert to do for you, because the solder points are very small, such that you have to sold them with the IC pins. Alright, that should be it, now have fun and enjoy your Wii.
