how can i sync so that the map lights turn on like the dome light when i open up the door

Mine always did methinks. Actually, I know they did, because they even faded off with the dome light after I shut them / locked the door.

mine too..

Run the wire for the map lights to the dome light power circuit for when the door opens?

but use a diode if you still wanna use them normally w/o the dashlight coming on...

where can i slice both wires together?

IDK off the top of my head. I'd have to look at the wiring diagrams and track it down.

Alright this ticked me off when I installed the map light RVM in my car. I still haven't fixed it but...
I have found that my car was not pre-wired for this light. I had to wire it into constant +12v, Grn to Grn obviously. The last wire needs to be hooked up to +12v with the dome light. Now the dome light is a negative trigger so it is always hot but it gets a ground connection from the BCM and the light turns on.
Now this wouldn't be an issue to use a relay to change polarity for the map lights, however the dome light is on a dimmer after the doors shut and if you were to use a relay it would cause the map lights to instantly shut off when the relay lost power while the dome light still dims. This wouldn't matter to almost anyone but me lol. FYI the wires run down the passenger side of the car to the back then to the front. If you would like to do this.
I am still trying to figure out how to get them to dim with the dome light.
It is possible that this does not apply to you if your car comes with the wiring for that light.
