Does the amber turn signals work with your method when you are done? The current PPV BCM programming uses the turn signal output circuits to operate the stop lamp lights. I needed to have the stop lamp output circuit activated in the BCM so that the whole LED tail lamp assembly functioned correctly.

No with my method, you lose the amber signal with my method. The tail lights act exactly as the US ones do where the red portion signals and brakes.

However, no BCM programming is required. So if you don’t mind losing the amber signal, and having them work exactly as the stock ones do (but you get the led appearance and brightness) my way is a cheaper method to get them running without splitting the additional signal line in the BCM.

I have updated the video to repurpose the amber signal as a reverse light.
