Sorry i am new to this...it's a generic trigger sm50cc and the engine I am putting in it is from a derbi senda which is the same engine they put in the aprilla 50cc all based on the minarelli engine the colour codes are as follows The colours on the replacement engine are a red and black wire, a yellow wire, green and yellow wire and a white wire. The ones on the bike are a white wire, a blue and white wire, a grey wire and a black wire. I hope this helps and thank you

Hello everyone....My wife bought me a second hand moped for my fortieth birthday, as I could use it to get about the local area and leave her with the car, it was also a thank you for me running the family home whilst she was in hospital for three months last year, anyhow she was ripped off and the bike was not useable, I got a friend of ours to look at for me and he put running the best he could. It lasted only a little while and yesterday the whole crank seized, I have sourced a replacement engine that fits the frame, but the main four wires from the magneto are different colours to the plug on the bike, can anyone help me please and advise me on a way to work it out please?
