Hi chaps Just registared and wanted to say thanks to the OP for his guide.....
and To put something back to the forum here are a few pics of the mk2.5 fuse box with the relevant fuses and relay positions.
......[REMOVED THE REST].....
I retrofitted factory DRL on my 2008 focus wagon TDCI. It is built for the german market with only basic equipment level.
The above applied to me also, had to change one on the connectors to a smaller size.
BUT, it didn't work anyway!
I crosscheck with the wiring diagrams, and two wires were missing from the main wiring loom.
So after retrofitting the two wires it worked.
So if anyone is attempting this mod on a mk2.5 with only basic equipment level then first check that you have cables at pos 5 in c103 and pos 15 in c102.
If not then you must retrofit the cables, and the biggest problem with that is finding the right crimping pins.
