I just got an '04 and would like to know how to get the rear hatch lights to come on?, they should work when you open the rear door. Also I am going to change to all 17" tires that have the same radius because are roads around here are so rough and noisy, any one done the same?

 

The cargo light is on the left side, there's only one. It will come on when you open any door or the hatch. The two lights in the hatch are the lic plate lights, turn on your parking lights and they will come on.
I am running the stock rims so I can't help you with the rims.
Hope this helps with the lights.

 

If you can't get the dome light and cargo light to come on, check that the slide switch behind the dome light is not in the 'off' position, which will never allow these on even with the doors open.

There is also a push button switch that forces these lights on regardless of the door position.

Can't say about going to 17 inch rims... HDDP has 18 inch rims all the way around for racing purposes.

 

I assume you are actually looking at the tag lamps. They come on with the parking lamps.
Many of us have thought the same thing so if that is what you are looking at don't feel bad.
I don't know about the wheels. Maybe post that question in the wheel section.
