today i got the new controller and installed it. the wires for the pedal sensors were not correct, had to rewire them. also the power connector was different. nothing that cant be fixed though. the bike is fully working again and this time its easy to connect the lights. It got a clear wire that will output the battery voltage when the light on the LCD is enabled. Next up is receiving the lights themselfs and the usb charger.
I would like to thank everyone for their help! Hope the bike will survive for more then 2 days now lol!
