Expert Reply:
If you already have a 7-way connector on your 2004 Tundra, then you would simply plug in the trailer. If you have the 7-way and the trailer is a different compatibility, you can use adapter # HM47570.
If you have the factory connections but are missing the trailer connector, then you would use the Hopkins Plug-In Simple Vehicle Wiring Harness for Factory Tow Package - 7-Way and 4-Flat Connectors # HM43385 or the Replacement Multi-Plug 7-Way and 4 Pole Trailer Connector # 20137. Both of these options connect the same way, so it comes down to your preference for look.
If you have the connector but your trailer lights don't function properly, I recommend using a circuit tester like # PTW2992 to test each function on the vehicle side first and then the trailer side. If you have issues let me know what the problem is and we can troubleshoot that specific function.
