I would be happy to draw some schematics and give you pointers and whatnot but first off, what are you trying to accomplish?

Do you want/need them to change colors? Do you want/need the remote for them or would a switch somewhere work? Do you want them on just with your control and/or triggered by opening doors?

There are a few ways we can go with this, ill kinda do a sketch up tomorrow and see what you think. I don't think the wiring will be overly complicated

Ok I drew up some circuits for you. These are for basic strip LEDs, not the system of colors with remote and stuff you linked us to. A roll of these 1 color LEDs are about $12 on amazon.

so if this is the route you want to go here are your options,
also I'm trying to show multiple led strips in parallel, don't let it look confusing

option 1A
what daktah mentioned above, LEDs are controlled by car

Option 1B
same as 1A but you can turn them on and off with the switch, car must be on for LEDs to work

option 2
leds will turn on any time you like without key on, will only turn on when you flip the switch

option 3
same as option 2 but we add a relay in parallel controlled by the dome light

adding control triggered by doors opening is possible but significantly more involved (door panel removal and running wires through the door looms)

let me know if you want to take one of these routes and the circuits can easily be modified to your liking

I think you are referring to option 1B... They only will have power when the car is on through the ACC outlet but you can turn them on and off manually as long as the car is on. If the car is off then the lights are off and the switch does nothing.

For starters if you are ok with one color you can buy the 16ft roll on amazon and make them yourself or I can make them and ship them, as seen on the left of the picture. Or go to autozone and buy the premade strips and cut them down if you like, as seen on the right
