Switching Relay With Open Signal

Hi, I'm trying to install a courtesy LED light above the driver and passenger door on a Ford Transit 2016 found the signal for open/closed door, however it is the opposite of what I need. Door open: N/C (open signal) Door closed: Ground signal If it would be the opposite would be so easy, power to LED one side, the Transit Door open signal to the other side and done. But now I'm stuck I can use Relays, resistors and diodes, but not much else to keep it simple Does any one have a suggestion how to connect it?

There should be a Gray/Yellow (-) output trigger wire at the BCM, Brown 46 pin plug (B), Pin 2. The BCM is located at the dash fuse box.~wirewise~ Verify all wiring with your meter before making any connections!

Thanks Wirewise! Is this a negative signal when door open? I will definitely check it out.

Wirewise, I found that wire and yes it works, but it acts same as the dome light, and for my application the light should be on only when door open and stay off when door closed. There is an output from Transit for the cab doors at the "High Specification Vehicle Interface Connector" behind the glove box. pin on pin 17 for Passenger door ajar (door closed=ground) on pin 18 for driver door ajar (door closed=ground) I need a ground when door open not when closed any ideas?
