White Led Car

I have a question about installing LED lights to the interior of my car?
I am going to ask a strange question, and please only answer if you actually know what you are talking about.
I am trying to install LED lights in my car's interior, but I don't know anything about the wiring in the car.
The instructions say:
"Connect the black wire to the chassis ground.
Connect the white/black striped wire to a switched power source (parking light, tail light, etc.)"
I do not know what or where a "chassis ground" is, and I don't know where the wires for my lights are.
I know I sound dumb, but I want these lights.
So how do I do it?
If it helps, I have a 2008 Dodge Avenger.
Chassis ground is any bare metal part of the vehicle. The entire chassis should be negatively ground to the battery. Ideal places I use are the stereo ground wire, cigarette lighter ground wire or any handily placed bolt/screw that I can get to bare metal with.
If you connect the live wire to the tail lights....then the LED's will only work when the tail lights are on.
My personal advice would be to mount a switch somewhere and run a switched live through the switch to the LED's, probably the easiest way to do this would be to get a multimeter and find a live wire that is only live when the vehicle ignition is switched on. If the cigarette lighter only works when the ignition is on then this would be an ideal wire to tap into.
Once you have your live wire located...disconnect the battery negative terminal and move it away from the battery post....you don't wany any live wires when you're slicing into them.
Either tap into your live wire using a scotch block, or for a real good connection carefully strip the plastic insulation back with a sharp knife...being careful not to cut yourself...wrap the a wire round it and solder for strength. Then insulate, insulate, insulate, make sure the connection is well wrapped in pvc tape so it can't earth anywhere. This wire then leads to your switch whereever you choose to mount it.
From the switch lead another wire to Black/white LED wire. Finally take the black LED wire to a chassis ground.....any handy bare metal and makre sure it is fixed well. I usually find a bolt that is in metal and use that to hold the earth wire.
Once all that is done you can reconnect the abttery negative wire...and turn on the vehicle ignition. That should let the power go down your new wiring to the switch....and depending what position you lef tthe switch in...the LED should be on or off. Flick the switch to make sure they work and job's done.
Keys to this are really thinking about your safety.
*Disconnect the battery before you slice ANY live wires.
*Avoid playing around with ignition wires and these are High Tension and not the sorta thing you want running through you.
*Insulate every connection to prevent short outs
If you are at all not sure about what you are doing then don't start the job. If need be pay an auto electrician to do the work for you...messing any electrical work on a car could lead to a shock, a vehicle fire or an electrical fault in the car...none of which are nice prospects.
