Hi Steve. I tried to post this yesterday and again this morning but for some reason it won't post. It's a picture of the harness routing in my car. And I believe it's the same in the Shuman car. If you enlarge the picture it should give you a good view of where the harness goes. It is tight in the area of the battery. When I reinstall the battery after a winter on a maintainer out of the car, I have to purposely move the harness a bit to fit the battery back into place.
Please PM your email address and I'll send the picture that way.
Chuck
