Having EU Taillights with US lights behavior is quite easy. Just changing the harness will work.
I'm currently working on the 100% eu setup (no sequential) - no Amber lights when braking or Red lights when turn signals.
I have had to route turn and braking signals from the right side fuse box.
Thinking about doing the same, but adding some vinyl edge to it after trimming.
Also it would be nice to have some kind of interchangeable / removable piece of Plastic, Carbon Fiber or Metal to be use as exhaust surround an be able to swap between different Exhausts
Something like this or...
Awesome.
It matches with my test notes with the multimeter. Switching a few cables + adding some amber vinyl should work to meet Europe requirements.
I will try it over the next weeks.
Again, thanks!
