I understand the Halogen conversion is pretty easy, but how about fitting a relay? And what would I need to fit a relay?

Hi Everyone, I was just wondering if anyone had any experience with converting to halogen headlights from the regular type? The conversion seems interesting since I saw it on the Canley website, but I'd like to know what I'm getting in for before I take the plunge. For information I have a gt6 mk 1. Thanks, Ben
