Word of warning... If you replace anything but the cargo lights, you will need error correction resistors or canbus bulbs.
Another word of warning, you should get as bright a RED 921 LED as you can for the 3rd brake light. The red portion of the lens will not appear very bright with a regular white LED behind it. Trust me, I know because I did the swap and had to go back to an incandescent bulb until I have the time to research one and the funds to buy it.
