08 focus DRL install
So i got myself a set of daytime running lights to fit to my 08 focus titanium. The DRL didnt come with a relay or anything just a grey wire and a black wire (on each DRL) is there a fuse holder for them in the fude box as some titanium had DRL as optional extra? And i want to wire them so soon as i turn my ignition on they light up, when i put my headlights on they dim? So i need to buy a automatic on/off relay ? Any help please?
