7 color LED to rumble motor mod

[JustWerkIt]

I am attaching an LED to my controller so it will light up when my motor vibrates. the problem is, when i pull the trigger the LED lights up but doesnt change color as its supposed too.all three lights come on, there just isnt enough power going to it. Where would I be able to connect my power to have this work properly?

 i tried this once what i found was that there never was enough power going threw the rumbler or was not constant enoughto be able to change color

ya i think its becuase of the pentometer's resistance on the trigger... so i decided to have the LED just run all the time. im just trying to find a point of power that i dont have to install anything to the board and am having no success

as i said i also did this  when i hooked it up to a contant power supply i used a light that would flash the colors then turn off so when i hooked it up the light would go through the whole motion but would then shut off

The rumble motors supply 2v and the other points that people commonly use are 3v. The 3v source doesn't only send power when the controller rumbles though.
