Controller port mod (LED)
First as you can see i didn't remove the entire metal shield, leaving the top part on (bottom on picture).

The pre-solder technique seem too unprecise to me so i decide to solder the resistor first then the led after (using tweezer), and connect them together once they where in place.
To put the shield back on i just had to clip it back in place then re-solder it whit the top part like it was (re-solder part can be skiped..)

Gotta be careful not burning the led, heating the resistor to much , unsolder wire or bridge them.
Most important thing is to be sure there is no short between wire, led and the metal shield!
