No ground wire in the ring- there needs to be a brown ground wire on the back. There will be a tab on the back that connects directly to the case of the tach.
Give me a call, I'll be wrenching tomorrow. I've got all the electrcial test stuff we need. I also have a spare door handles you can use untill your RS panels come in.
