New gy6 and new harness dont match up for plug and play
 

So i got this roketa gk01 from a friend for my son. Bought a new gy6 from amazon. Cleaned it up got it going but i was melting coils. Stopped running it got a new harness but it doesnt plug in as easy as i thought it would. I need to know what cdi and what voltage regulator i need so it plugs right in without having to chop up a new harness. Thank you gentlemen
