That is a picture of the CDI box that the guy gave to me so I assumed it went on this bike and it probably did it one time it has three wires I would imagine are the input which are red green and black then a single wire and then a blue and white wire together

It does have some white lettering on the side where the wires come out but it definitely looks like it has the same color wiring is all the pictures it's just the bike does not have the three wires coming out of the pick up

Yes one of them the white one is connected to the coil I posted a picture of that the blue one is just dangling but the backside of the bike has the wiring with the black red and green would look like they go to the CDI box

red, black and green are shown going to the nosecone black being a ground lead for testing so red and green would connect to the module white and blue to the coil

So what you're saying is that the CDI box the single ground by itself is obviously ground to the bike the three clumped wires together which is black red and green do come or go to the pick up but the black is not used that's for testing and then the last two wires which are the blue and the white go to the coil correct ? Now if I have blue and white coming out of the pick up which one goes to green in which one goes to read and then when they go up to the coil what side of the coil does the blue and the white go to from the CDI. Thank you very much I feel like we're getting somewhere lol

So I like that we're getting somewhere but why doesn't that make any sense that all the wiring diagrams don't show that extra wire or black wire as a test lead they all show them connected straight to the pick up ?
