Thank you! Already swapped the cdi unit and the coil. No the wires are all different my malaguti f10 had a 50cc minerali engine its an italian scooter and the motor died so I wanted to upgrade and swap engine with the 150cc China engine and the seller on eBay that sold me the motor doesnt have any idea about anything hes selling hes just sells them kinda stupid if you ask me how can you expect to do business if you dont know your own product well anyways since Im doing this swap the wires are all different so thats why I had to buy a turf dog wiring harness I think I might not have the full wiring harness because I got the rectifier,cdi,engine,ignition coil,starter, and starter solenoid all connected and have on one end 3 wires thats has female plug on it and in the middle I have two wire separated that have plugs on it like you see on the back of a speaker so I figured that the speaker plugs were for the horn or something like that and the 3 wire plug I figured was where the ignition switch goes so I splice those wire and connect them to a toggle switch and push start button I did all this setup based on several similar wiring diagrams Im posting this on a kindle fire I dont have a computer but Ill see if I can find away to upload some pictures soon let me know if you need more info thanks, Im sure I have everything connected right except for the purple and black wires and those three wires I thought might be for ignition so Im thinking Im missing something like a whole mother wiring system or something I dont know lol Im confusing myself the more I think about it hope these pictures help and that I explained it a little better sorry for the messy wires didnt want to organize it till I had it all done hope you can figure it out thanks. 3) Regulator Thanks to this guide I found out the Stator was not producing a correct voltage so I ended up replacing the CDI, Coil/Plug wire , spark plug and the Stator.
