Quick question everybody. I have attached a picture I found on the other post of the back of my command unit on my 03 e55. If someone could just please tell me which wire is the illumination wire, the ground wire and the v12 power wire that would be great.... I think the v12 power wire is the red white one but is it the switch kind or the constant power kind (and yes i do know the cigarette lighter has the switch kind 12 v and its colored red and white)? I remember reading there were only two 12v sources in the car the rest was something else. Thanks in advance
