Coolster 125 pitbike question
 

Just picked up this coolster 125 for cheap guy said it ran with starter fluid. Engine looks clean. Cleaned the carb put new gas etc. But theres a molly plug under the seat not connected to anything. There is another connected to a little black box. But the one with nothing has a pink wire, purple wire, blue brown wire, green purple wire, teel brown wire. These coolsters dont have keys. Unless someone changed harness and theres no key????? Ot traces back to the stator…?
