That is sad. Wish I could tell you where it hooks. That is why I had my cluster redone on my car. The Meck. for the speed O was shot on mine and the guy had parts to rebuild it. That cost extra and told me the parts to fix it was getting scares. Hope you can get it fixed. Is there a speed odometer shop in your area. They may be able to help. Good luck and hope you get it fixed soon.
