You may want to look at the original thread on this as the color wire seems to go from green/white or brown/white or even black. Not sure if it's a model type CX, CXL or model year that this could be the issue. I'll assume I got lucky and my harness matched the installation instructions.

You can try the online Chilton manual, but scroll down in the post as there is a new login and password, it has wiring diagrams which could help.

Nice follow up and information on location as it may help others facing the same thing, glad to hear it's installed and operating.
