I do have a solution for you. In order to add a 7-Way wiring harness to your 2001 Toyota Tundra, you will need to start by adding a 4-Way, # 118378, if you need one. I have included a link to the installation instructions for this harness for you to view.

With a 4-Way installed (or using an existing 4-Way if applicable) you will then need to install a 4 and 7 Way Installation Kit, # ETBC7. This kit includes everything you will need to install a functioning 7-Way on your truck. I have included some links that explain how the ETBC7 is installed.

The links mention the installation of a brake controller as well. If the trailer has a 7-Way connector, then it probably has electric brakes. For a brake controller, I recommend the Tekonsha P2, # 90885, because it is easy to set up and easy to use. I have included a link to the installation details for the brake controller as well.

It sounds like you are speaking of the wires for the brake magnets. If this is correct, you will need to connect one of the wires to the brake controller output wire on your trailer connector and the other wire will need to be grounded to a clean…

That's a very good question, we tend to be extra cautious and say to use 10 gauge wire because that would be more than enough. When you get into longer trailers that will end up using a lot of wire the heavier gauge wire becomes more necessary.…
