Went to the bike shop today armed with the light and to pick up the visor screws I had ordered a month or so ago. He said the LED is just a type of parker light and is not needed. I have since put some heat shrink over the end of the two cables so it can't accidently arc out and plugged the harness back in. I figure if the harness is there and myself or someone else feels like replacing the LED at some point then the harness will not be missing.
So went to put it mostly back together tonight, and run into some problems, ie, missing parts. Whoever replaced the visor has left out two rubber screw-backs, which is not the end of the world as they won't be expensive and I've removed two from another spot which is easily accessible and put them in place of the missing two, which is fairing off to replace.
However, someone has been in their and played because there is also missing grommet that goes over a locating post on the fairing. Leaving it off could mean the post eventually snaps off from movement. So emailed the bike shop and have asked them to order me a grommet and two screw backs.
So while the bike is kinda off the road waiting for Triumph to replace the fuel line adapter, it could still be ridden, if needed but without these three parts I can't put it back together. So at a guess it's at least a two week wait for parts to arrive. Some people should not work on cars or bikes, or they should learn how to do a job right the first time.
