Fitted my towbar last night. Had wired up most bits the night before so it was just a case of bumper off, fit towbar, run cable up to relay and connect and refit new bumper with insert fitted. Job done. Was all made a lot easier thanks to this forum though! Really helps when you know what your looking for, where things are etc before you start. So a big thanks to everyone on here!

For those interested I fitted a Westfalia dectachable towbar and TEB7AS
bypass relay to my 2006 MK5 golf GTTDI.
