ah ok didnt spot that! just plug it in and you'll be all set wiring wise. along with the 53 relay you need the different headlight switch which has 2 clicks for front + rear fogs
interesting, i just swapped looms, and hey presto, is it cos its a gti 8v already? and this is a gl.. so should i of fitted a relay? lol cos 6months and no probs, (touches wood!)
