Hi Think that's what I had hold of and unplugged the top 3 wires 2 grey a blue stripe and I wasn't sure if it was a bolt or screw further down but I didn't want to take it off encase wrong. The spec page you have a pic of don't no if its the same one I have on disc manual but cannot find out on it yet. cheers once again.
Hi got it off must of been first time since it was new . Very tight rusted up first few threads when I got it removed it was fully carboned up so it must of wanted cleaning for a goodtime .So got all the carbon off front and plenty came out from inside. Got it back in and tighten so I will have to reset it too take the light off and see if it stays off while I'm driving about. Put a picture up to show what it was like.
