If you have isolated the problem to the 7-Way connector on your 2002 Dodge Ram 2500 then you will want to start off by looking at the connector itself. Check to make sure that there is no corrosion built-up inside; if you find any (looks green or white) then you will want to go ahead and clean it out.

If your Ram has the OEM tow package then you might need to replace your connector if you clean it out but the wiring still isn't working. Tekonsha has their Multi-Plug T-One Connector Assembly # 20135 which has both the 4-Way and 7-Way connectors like it sounds like you have. If this is what your connector looks like and you are getting the signal on your 4-Way then something internally is going on.

If this is not the setup that you have just let me know how your wiring is run and I can help you troubleshoot further.
