no you need a full agu engine loom with a plug for everything on the engine plus the ecu, it comes in 2 parts like the loom in the thread and should look pretty much the same there aren't that many differences between different 1.8t looms. The end result will be mk3 loom at fusebox side and mk4 loom at engine side
I'd suggest if you cant make full sense of the thread then don't attempt it yourself. I considered doing my loom myself but when I got both looms together and sat down to do it decided it was a bit beyond my skills, there are people around who can do it for around £100 if you supply the looms and in the grand scheme of the conversion that isn't very much imo. I had mine done by Rubjonny on clubgti or f17bad on here has some contacts as well
