Footwell lights

[6thdiesel]

Hi I'm new here and recently purchased a bare bones 2018 3500 G56 cummins. I wanted to upgrade some lighting and ordered a pair of footwell lights & bezels. Tried plugging into connector stowed under the drivers side the light didn't come on. Checked for voltage nothing with door open. Reading other post I thought this would be plug & play. Has Ram made all options dependent BC module programing? or I'm missing something. Thanks for any hints?

Update I'm at a loss what's happening. Prior to trying the the footwell light I had disconnected the overhead center dome light. When I plugged it back in it wouldn't come on. I then started the engine and presto dome and foot lights are working. So you disconnect a component or connector the affected system goes into lock down until restart?????

My dome light has a time and will turn off after 5 mins I think it is to prevent draining the battery

I’m well aware of the lights turning off after a period of time. The situation I experienced even after closing doors a number of times lights would not come on again until I restarted. I have completed the addition of the footwell lights and an overhead console and all is working as it should. Completing this task was a little different from other posts on the subject. On cutting through the headliner found a green connector glued to the top with one wire yellow/green that was powered. I used it to power reading lamps and cup holder light. The courtesy lamps and ground I tapped the center dome light (crew cab). While working inside the cab, doors closed, if I cut a wire or opened a connector what I think was the BCM would softly whirl or buzz cluster lights come on and off. Very sensitive to changes.

No aware of any lighting wire under the seats.

Depending upon trim, there may be wiring under the rear seats...ref lighting
