Where to Attach the Extra Brake Controller Wire Harness Ground Wire on a 2006 Toyota Tundra TRD 4X4

Question:

I bought this pigtail from you for my 2006 Tundra 4x4 TRD. It has an extra ground wire to connect somewhere? Where does it connect?

You will need to connect the extra ground wire to a good clean, paint, rust and corrosion free part of the vehicle chassis. If you can find an existing ground stud under the vehicle dash this would be a good choice. If not use a self-tapping screw of the appropriate size to attach the ground wire to a solid point under the dash, making sure not to drill into any existing wiring, moving parts or an exterior panel of the vehicle.

A good way to check the ground location is to use a circuit tester, item # PTW2993 if needed, and attach the alligator clip to the ground location and touch a known 12-volt source with the probe. If the light lights brightly then the ground is sufficient.
