tbh I cant remember it was over a year ago when I id mine, I think they are on the inside around where the piston comes through near the brake pedal. here's a diagram of the setup

Just come back to this post to say a big thanks, engine loom is now out, not easy at all I had to remove steering colum in the end to gain access to the bolts to the master, anyone doing this I can say if you do this you will save time as I spent 2 hours looking at how to get round it without removing or loosening things off and in the end took 30 mins to do the above and it was out.
There's no room at all behind and by pulling on the loom your at risk of damaging the wiring and ending up with a harder job of re-wiring if you don't loosen off besides I don't think there's room to pull it without doing this, someone might correct me on this.
