I have 15 PIN connectors so used the before 03/07 step. On the post when I said "(that's 1-5 on the bottom, 6-10 in the middle)" I just left out "11-15 on the top" for brevity but if you look at the picture they're there. If you have 10 PIN connectors you should surely use the after 03/07 step - PIN 7. From what I remember, the front of your fuse box did look quite different from mine.
