No Driver Brake Light After Installing Curt T-Connector Vehicle Wiring Harness On 2017 Toyota Tacoma

Question:

I have a 2017 Toyota Tacoma, I just installed the wiring harness and as I tested it I noticed that the driver side brake light stopped working. I tried switching the bulbs from the passenger side They work fine, and the brake lights also did not work once switched. I then tried reconnecting the stock connectors and still the driver side brake light doesn’t work

I would first check the fuse in your engine bay fuse box for the driver side brake signal. That's really the only thing we can help with that would cause this. I have not heard of a harness such as the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # C56349 for your 2017 Toyota Tacoma causing an issue like this before. If the fuse checks out, It might be time to visit a local dealer.
