Yes it will work, Only thing is the '03's have 1 extra light I think. Not a biggie though. I just didn't use that hole. I know on my 99gmc I had to modify (hack) the mounting holes a lil, but it works. See sig pic

I just did this to my truck this weekend.All you need is the harnesses.

No slicing or hacking involed took me like twenty minutes.
I would recommend the harness they will run you like 20 bucks. If you so use your 3 bulb harness with the new lights, the light sockets(thing that twist into the light and lock) will be dif and you will have to modify your tail lights. just get the harness and do it the right way.

If you don't want to spend the extra money on the harnesses you can do it this way for a lot cheaper. 3 years on my setup with not a single problem. The size of the tabs on the light sockets are a little different but it's not a big deal.
