Happy New Year Everyone!! Does anyone have or know the wiring diagram for the window switches in the 451? The passenger door switch has 4 wires... Purple/White strip, Purple/Blue strip, Grey/Blue strip and solid Brown (I haven't looked at the driver door yet). My guess is the Brown is ground to both the window motor and the light in the switch but I need to find out for sure what two wires are indeed for the light in the switch. I want to add lighting under the door pulls that will shine down in the door storage compartments on both doors. Thanks for any help Craig.
