Nintendo Wii combo Component/Composite Cable

Step 5 Slide casing back on and connect switch and phono jack

The next step is to reassemble your cable. I found that by feeding all of my wires out of the "bottom" of the cable (the side that has a "don't throw in trash symbol"), I was able to get everything out and everything else put nicely together. You'll want to use a fair amount of electrical tape in this process to ensure that all your connections are protected and to help keep the wires together as you bring the casing back down over the plug.

The next step is to solder in the switch and phono jack. Unfortunately, I didn't take pictures of this process. On my cable, the switch is soldered between the two black wires. Since you've got a SPST switch, it doesn't matter which connection gets soldered where. With regards to video, the yellow is the composite video signal and the blue is the ground. I soldered the yellow to the center terminal of the phono jack, and the blue to the ground terminal. It can't hurt to give it another test at this point before you tape everything back together.
