Just installed a garage door opener. Got a $17, two button opener from Amazon. De-soldered the buttons and soldered wires into the holes. Put the opener in the space under the Goldwing label and ran the wires forward and up the bars. Installed a Harley-Davidson odometer reset switch into lower right control section. Works great. Of course, mine is nowhere near as good as what is arguably the best garage door opener ever...
