Former, I feel that wouldn't be a big deal, just tap into one of the wires that goes to an ambient light bulb, and run that wire to some leds that light up the cup holders somehow.
Gkinla, I am planning to wire a separate dimmer knob along with the leds that will dim the ambients separately from the dashboard. If I get this all together, I will post pictures.
I am eagerly awaiting any info you get from the dealer.
I picked up the car this morning and everything works as posted above, except when opening the door during the day the parking lights and ambient lights come on. Everything shuts off when closing the during the day. Again, I have automatic headlights.
Unless the dimmer is rated for LEDs you might get flickering when reducing the voltage to the circuit. Then if you use a continuous 12v circuit, not the dash dimming circuit, this condition might not happen.
For what it's worth, here is the statement from the RO regarding the connection point. "Wired into Smart Junction Box, pin #3, blue/gray wire". I don't know where the Smart Junction box is, maybe the fuse box under the hood. Then again it's more info than we had before.
Another connection point I thought of is the cigarette lighter circuit. It powers on when starting the car and when shutting down, powers off in several minutes or less.
My dealer found this switch to control the Ambient Lighting, it replaces the switch supplied in the Ford kit. Functions as on/off and color cycling. I think you're doing your own install so this is for info only. Part number DG9Z-13D730-BA, $28.00. replaces the auto park switch if equipped. Auto park still works. This prevents drilling any holes in the cup holder trim.
