I bought 2 blade E scooters from someone on craigslist and need a wiring diagram

Blade E scooters are products of China, so you would need to contact the manufacturer to acquire the factory wiring diagram. Usually the manufacturers are very allusive and hard to contact, so if this is the case with your scooters, you can try this online scooter parts store. They have a "find a repair shop" feature that will provide you with addresses and phone numbers of shops near you that will help you.
