haveney heard of a relay being needed at all?

the plug is there, as they are in the bay, even on my 1300, but its jsut finding it, it changed on a chassis break in 1991.. so wether some of the late 90specs had mk3 plugs or what, im not sure.. as john said to me on the oom they fitted to j_s' car, it had a red 2 pin plug the other end, think this is the one ima need to source fro vag rather than the T plug i have already.
