This is a total shot in the dark, but I noticed above that you mentioned trying use a tail light mounting screw as your grouding point for the converter box. Not sure about the monty, but on some vehicles those screws go into threaded plastic clips instead of bare metal. Just a thought.

Make sure when you're testing the connector that your test light is clamped onto the bare ground pin on the connector, NOT onto the frame or bumper.
