Negative, it is not a feature on the US models for flashing brake lights.Had all the covers off. Cable comes straight from the rear cluster and plugs in. No modulator in sight. Loom is still nicely taped right up to the socket, so no modulator fitted before the socket. Wondering if there is a modulating bulb that I'm not aware of. Or does the US version have a different software that makes brake light flash?
That is where I put my modulatorThere must be a modulator. Remove left side panel and under the seat tray there is a 6-way connector (only 5 wires) where the rear lighting harness is connected to the main harness. Sometimes that is the favourite spot to connect aux. rear lighting. Blue wire is tail light, yellow is brake light.
