What battery harness do I need to connect to this from the battery?
It's going to depend on what type of controller is on your Pride Legend SC3000. Please call us at 1-800-798-0325 or email us at contact@monsterscooterparts.com with the serial# from your scooter and we can find out the correct battery harness for you. The serial# will be located either on the seat post or on the rear of the frame; it will start with a letter and be 14 digits long.
