The standard courtesy system in the Ram uses halogen bulbs, the upgrade Led system uses three wires to power the 2 led package. --- one for courtesy the other ambient..

I robbed the IP ambient light wires from the donor harness and rebuilt them into my truck. Added the 3 IP lights, replaced the footwell lights and replaced the headlamp switch (2 wheels and rear fog light function--I'm optimistic). Did the Alfa changes

Everything works; but I have a curiosity question. The panel lamps, including cluster, dim with one wheel. The footwell and IP ambient dim with the other. However the small light in the overhead console stays constant. It's not a problem; but wondering why is doesn't dim when its connected to the same WT/GR as the footwell and IP ambient lights.
