kenr74 Posted February 11, 2004 Report Share Posted February 11, 2004 Ok, I've seen this post here before but I can't find it. I have a 99 with a bad CDI. I bought a 96 CDI on here but the plugs are different. Does anybody have a diagram of how to wire the plug. My 99 has a plug with 5 wires but the 96 only has 4 wires going into that plug.

jrfastbanshee Posted March 4, 2004 Report Share Posted March 4, 2004 You should be able to wire it color to color. The extra wire is green/yellow stripe. That wire is for the park brake rev limiter...why the hell yamaha thought we needed that I have no idea! This SHOULD work fine...however...I bought a 2000 cdi for my '87 shee. Works perfect on my '97 but when I rewire it to my '87 (leaving g/y wire dangling) it work spark at all! If I leave the g/y wire dangling on the '97 it still works perfect. The wiring diagram shows the rev limiting when that circuit is grounded only. If anyone has rewired 5 plug to 4 plug or the other way please let me know if there is any tricks! Could yamaha changed the wiring somewhere and this won't work? All the diagrams I saw show the same scheme minus the g/y wire from '97 up? Please help!
