Blinking 3rd brake light with right turn signal on my 21 Crewmax

I've installed aftermarket LED emergency lights (on both sides of my license plate) and installed the 12volt Solutions Third Brake Light Pulsing module. The install is really directed at the High mount stop light (I didn't want that light used, as well as not pulling down my headliner). We tied into the wires seemingly right before the split to the trailer connector.
They work as expected, except that they blink with the right turn signal.

Any suggestions on moving my tie in up stream or into the fuses or a completely different way?

Are you just looking for a pulsing additional light? If so, I bought the Diode Dynamics HitchMount LED Pod Reverse Kit. It already saved me a few times and is super bright. Easy to install and remove.
