Moving on to another project but have come to a stop with this one Looking at wheel controls, specifically illumination, i have not yet found a set of controls that are backlit that are the same So time to pull a set of controls apart, as you can see they have pcb locations for the 6 resistors and 3 leds (R1-6 and LED 1-3) the main switch body has the cutouts, but the switch cap are opaque black plastic   Right hand Phone controls, again it has the locations on the PCB
