I was exploring my 420SEL while I had the cluster removed for some bulb replacements. I failed to find the illumination power while I was attemting to installed the auxiliaury terminal block below the parking brake pedal.
This is the same block used for 560's for heated seats and other extra powered devices. I have the other 4 wires connected but the 5th for the lights is not.
Any helpful hints would be greatly appreciated.
