The pursuit doesn't have interior dome light. Only a bit round light in the ceiling with a manual switch to turn it on/off.
The cool thing is that the dome can produce both white or red light.
As mentioned earlier I wanted the light to turn on when the door is opened. This is not enabled in a pursuit car for some reason.
To do that I found a signal in the right A-pillar that would give a high voltage when door is opened. I also found the power wire to the dome and merged the wires.
The Red/Blue wire is the power to the dome light. The Yellow/Purple is the door ajar signal.
The problem here is that sometimes you need some extra interior light so I did some modification so that Aux1 button on the steering wheel could also turn on the dome light.
Again the diagram is simple but the wiring is a lot harder.
Door is the Yellow/Purple.
Acc is the accessory power I found in one of the connector from the upfitter document.
