Ive contacted just about every major rotary shop with this question but no one has any answers so i thought id try the forum.

i have a 20b that im almost done wiring, but im stuck on the ignition igniters and coils. On one part, there are Green, Green/white, Green/red and Green/black wires that im not sure where they need to go. If anyone has a stock wiring diagram or info relating to a 20b i would really appreciate it! Im stuck right now on what wire does what!!!! Please help :-)

 

there was someone on this forum with a cosmo manual i am not shure who though

 

I have it but it might be a couple days before i have time to check those colors out

ok i am not going to be much help all the factory wiring diagrams tell you is that these wires go to the computer
nothing about what they do. that will take more thought.

the coils are simple, theres 4 pins the one off by itself is the 12v power and the others are 1-2-3. the ignitor is a different ball of wax though. theres power, ground (i think) a tach output, and then the 3 inputs and 3 outputs. unfortunately whats what isnt clear

 

Thanks for your help. I was able to get a japanese diagram from a rotary shop (thanks to them) and after awhile i think i got it right. I agree that the coils are easy, but the ignitors werent so easy! Hopefully it will all work out. Thanks everyone...
