Based on the troubleshooting you've done so far you have a shorted out converter box of your trailer wiring harness. The only solution in this scenario is a new harness. For that the Tekonsha brand like part # 118413 is our most reliable option so it would be what we recommend for your 2004 Toyota Highlander. I checked our order notes and was not able to find you in our system also. Based on that I don't believe you bought the kit from us.
