No, not that one.........!
...I've just finished hunting thru my hard copy 'collection' of many of the BRILLIANT mods, etc that have been posted on SeaX and Xweb over the years!
I found my copy of Ulix's little gem re the ' park light' mod discussed above - it is titled "Here's how to do it on a 1300" , the post is dated Jan 23, 2000!! (You may have to call out to JimD for help in finding this in the N54 archives - I gave up after about 10 mins fumbling thru them)
As DaveM has said below, this mod suits X's with the ceramic bullet-type fuses - dunno if it works with the later type fuses.
Hope this helps!
