I was after some info on installing an hour meter on my YZ450F (2005). I want to make it as discreet as possible and have 2 questions: 1. Where is the best place to ground (earth) the hour meter. There is a metal loop on the end, is there a bolt that I can undo to bolt the earth to the frame? 2. I am going to wire it into the kill switch, could someone confirm that I splice the wire into the black wire with the grey stripe through it? Pictures would be awesome to help me picture it. For those that might need it the hour meter is a motominder. Thanks in advance.
