I am rebuilding a 91 900ss the only thing I need to do now is connect the coils to the igntion modules (bb1105) There is a 2 pin and a 3 pin plug on each module. I need to know what each of the 3 pins on the 3 pin plug attaches to. Could some one describe this by looking at there bike. Many Ducs use the same set up. Even a digital photo would help me immensly
