Have RV Questions? Ask an RV Mechanic Online.
I am attaching a place to try. Also look on E-bay Motors if you haven't already. Please get back to me if you don't find any there and I can suggest several other sources. Thanks! All follow up are included in our fee.http://www.novak-adapt.com/catalog/electronics/sensors
I am informed that Rostra took over from Dana and so you might contact them as well for this. Please let me know how this turns out.http://www.rostra.com/support/
Just checking back to see if that information I provided was helpful here? Did they have what you needed?
