Okay,
The install is actualy quite easy on the X2 Lite (I presume its the Lite and not the Pro you got)
If you use the pogo pin header then you only got 1 wire to solder, its a bit small but not so that its really hard to do, just pre tin the wire first, and then tape it to the PCB lined up with the pad you are going to solder it to.
The Pogo pins are dead easy to solder in, no explaination necessary, if you have a v1.0 xbox then you may need to desolder the points (the v1.1 doesnt have solder in these joins)
