tion or any solution. I want to upgrade from a Nutone IM-4006 to a IMA-4406. I have a flat grey six wire imbedded with a flat female bar across. It is imcomatable with the wiring on the 6604 which requires a seperate 6 point installation. Looking for a wiring harness solution or any solution. I called Nutone and they said there is no harness. Is there a generic one I can purchase. Only other solution was to strip the grey wire and make the connection. Since this only an upgrade and the wires are so small, I don't want to do that. Thanks for your help.
