The previous shell on my '04 Tacoma was not an LED 3rd brake light and I wired it up by splicing into the brake lamp wires at the rear of the truck. It worked fine. This new shell has an LED 3rd brake and when I connect the wires that are connected to the brake light and press on the brakes it does not work.

I have tried all combinations of the wires.

I can even get the dome light to work off the brake light connection.

Confirmed the brake light is good by connecting 18v cordless tool battery to it.

Multimeter reads 0.8v coming off the truck brake light.

It seems as though the 3rd brake light on the shell is not getting enough power. I have a 7 pin and 4 pin trailer connection as well if I need to utilize them. Any ideas on how to get this 3rd brake light on the shell to work with the brakes?
