Sorry for the wait on the write up, my running arouns took a lil longer than expected and I worked night shift last night but here we go.
First step is to remove the stock signals, look under the headlight up near the triple clamps you will see the stock signal come through with a 12mm nut holding it on and the wires comeing out of the end running in behind part of the fairing. There is a small phillips screw (star) where the wire run behind the fairing. Remove the screw and pull the wires out. They will take a lil tug to get them to come out but they will. Unplug the wires and remove the nut holding the signal on.
Next step, I drilled a small hole beside the stock hole for the signal to allow the wires come through.
Now its time to install the hotbodies flush mount. Put the proper shim on for the side your working on and I used 5 of the supplied washers to get the new signal to be flush. It may vary from bike to bike. Feed the wires through the hole you drilled and push the signal into the fairing. Add/remove washers if needed and use one on the backside with the nut to attach. You dont need to tighten them to much as they have very little weight.
There is a metal bracket that supported the stock signals, dont use it the bolt isnt long enough to keep the signals flush plus like I said before. The flush mounts have no weight to them. You can either turn it out of the way or completely remove it. I have mine turned out of the way and it doesnt interfere with anything.
Hope this helps and any questions or problems just let me know and Ill be glad to help
