what ended up happening here? got it fixed?

Nah, haven't had any time to dig into it since then. Hoping to soon.

Hate to dig up an old thread from its grave, but did you ever fix your flashing problem @spike021? I’ve got a Valenti as well bought from FTSpeed doing the same exact thing and have yet to solve it. Some dude from another thread said to try giving it into own independent ground away from the taillights ground, but hasn’t worked on me still.

Hey. Sadly no update, been a busy couple years. If you figure it out, definitely let me know. One of these days I'll probably just pay a shop to do it at this point. :sigh:
