I will get a picture for you later today. Currently 8.50am here. All I have is a bolt (so that it is removable whenever) that fixes the lower ends of the frame to the front wheel arms, just in from the kingpins. Of course, the flat face of the frame does not match the angle of the trike frame so I had to come up with how I was going to ensure that the faces bolted together. It is a short length of square tube sliced end wise to make two angled fittings - one in front of the wheel arm and one behind. The bolts go through the dashboard frame, one half of the fitting, the wheel arm, and the second half of the fitting. Easier to show in a pic than words. As I said, a picture later today.How is it mounted on your frame?
That is what I want to use. They are small and easy to use.If you are only going to charge your phone, a battery bank type charger might be the easiest/simplest/cheapest. You will end up with the phone battery time plus the battery bank. Charge both at night and you are covered.
You could easily attach another cable to the shift lever and run it up to a remote indicator conveniently mounted somewhere.Warrior Modifications Update:
The only problem was that the shift lever in its current position does not provide visible feedback regarding its relative position status.
