I did it on my box, but have 99'. I am really glad i did it. I don't know if it's the same for the 03 or 04 tho. It only takes one click on my e-brake, but don't think the hack really affects how many clicks on your e-brake it's going to take.
The hack is super easy, and if you are sketch about doing it, it says the part is onl $40 bucks anyways.
part number 986.618.111.02. $39.50
Good luck.
