I added one of these modules from
Blinking Smart Products from KAH Technologies to my rear fog light.
It gives six quick flashes and then leaves the light on when you step on the brake.
I also got my tracking number from Sam. My TT kit will be here on Thursday. I hope to be able to start the install next weekend.
This will be another home install. I'll be doing it without removing the engine.
I'll be sure to add pics as I go.
