Please note:
The only real way to test your CDI box is to swap it out with another known good unit from the same year/make/model. Because of this, we recommend that you rule everything else out before replacing the CDI box.

Our CDI may use a different wire color code then you?re original.
All of the wires are installed in the correct order; please do not change any of the wiring configurations.
This CDI is designed as a direct plug-in replacement and should be used as such.
