Did you try NAPA? Take it to them and let the parts people look at it if you have a store in your area. - pushrod
If NAPA doesn't have what you need , maybe there is a trailer/motorhome sales in your area. Anyplace that does installations is more likely to have a variety of harness adapters. - ziptie12
or even a u haul rental store - globalhelper
