For some reason the installation instruction link doesn't show up so I have copied the instructions to my blog :)
Scroll down for the black and white stair instructions!

TO INSTALL "Maya Build - Wood Modular Stairs"

(1) Place your downloaded stairs file in your 'Downloads' folder as usual.

(2) Find where you originally installed The Sims 2 game (not the expansion packs) and look for the folder TSData/Res/Catalog/Scripts. It is usually in THIS location:

C:Program Files/EA GAMES/The Sims 2/TSData/Res/Catalog/Scripts


(3) Open the file 'modularStairs.txt' and find an empty space at the bottom of the page.

(4) Copy and paste the following block of text below into a space at the bottom of the file:

# BitzyBus-MayaBuildModularStairs060506-MESH
modularStairs 850

objectID placeholder 0x00209C08

objectID topStep 0x00209C07
