I have no clue where to start. I went to this place: http://64.4.22.250/cgi-bin/linkrd?_lang=EN&lah=3f093c77359552871285b99e3e59a247&lat=1030854967&hm___action=http%3a%2f%2fwww%2embca%2eorg%2fw124%2ehtm

but I'm still somewhat lost. The installing instruction is for the W124. Somehow I thought I wouldn't need extra wires for the installing. From looking at the site, do I really need all these wires and things for the installation? Can someone give me the basic steps I need to do for W201 euro installation? I know I will need bulbs (how many? I'm confused by the H3/H4/H5) and pin connectors (what are these as my euros did not come with them?). The euros I have are DEPO W201 euros. Thanks!
