After reh8388 made one for his 2010+ bike he made one up for me to try out on an '08 bike.
Took about 30 minutes to install, program and put the bike back together. If I was not taking so many parts off so that I could get better pictures I would say that it's a ten minute job.
The '08-09's are setup a little different than the '10+ but for the most part they are the same.
The '08-'09 have the head light relays in a different location. They are located on the left side where the '10+ bikes have the storage compartment.
Start by removing the three screws holding down the left black panel.
Lifting the panel out of the way (be careful there is a plastic rivet holding the top to the dash and they do break easily) you will find 3 relays. The online data shows the headlight relays to be #26.
I removed all three to see for sure.
In reh8388's post he states that the brown plug is the one you want. I used a 12v test light to quickly verify this to be the correct relay on the '08 also.
Next remove the relay and plug the female end into the bikes harness in place of the relay. Then plug the relay into the male end of the harness.
Stuff the wires down in and push the relay back onto the post where it was before
AT this point I followed the programing instructions that reh8388 included with the unit. It took it the first try, then I had to program the opener to recognize it.
Now that I know it works I needed to mount the sending unit to the bike.
The back side of the panel works perfect.
Although there is some heat shielding that needs to be removed first.
Once it's removed and cleaned off all you need to do is to remove the backing on the heavy duty Velcro that was already on the unit and press it firmly to the panel. Hold for 20-30 seconds and you are good to go.
Install the panel and you are done.
Here is a short video of it in operation.
