Pride Sundancer mobility scooter diagrams and schematic

[mrgus2u]

I have an old scooter that is missing the horn, i want to add lights to it, and more importantly, is randomly coming in and out of gear. Pride is notorious for totally discontinuing support as soon as the scooter line is discontinued All i can get is the user manual, and a parts list(and most parts are now unavailable). I can figure out the electrical part by using the controller schematic, which I , and the gear problem is probably stemming from a rusty brake solenoid, but I really could benefit from a mechanical diagram , and the wiring diagram would save from having to trace all the wires manually.
Can anyone help?
