interesting.. so everyone says HOW did you install the LEDs.. so i found some pics i didnt remember snapping.. here is how i did ONE of the extra LEDs.. maybe it will help all of you that are having such a hard time with it
ONE of my dim spots was the 60-80 mph area.. this is the install of the shaved socket in the cutout cluster housing
the light alone was TOO bright so i had to use this extremely high end light redirectioning cover (duct tape) to even it out.. it might look ghetto but it works FLAWLESSLY.. i made little light covers out of clear bubber tube painted on one side to replace the tape if it ever fails..but i doubt thats going to happen
running the wire OUT of the back of the cluster to tie it in to the other wires
to power the extra LEDs i tied them into the wiring for the top two lights..
hope that helps solve some of the great LED mystery..
