I recently posted about Integrated tail light but no one seemed to have been so interested in it. But today I removed my tail lights and snapped some pictures of how the tail lights are wired to show it to you guys and see if anyone can help out.
I was thinking of something easy that can be easily plugged in with no cutting or at least at minimum.

I was thinking of a male 7440 type plug to plug into the turn signal, that has the power and ground which would be best if it was a male/female plug so it could be connected to the tail light connector.

The last picture was made and I tried ordering it but apparently the website or the brand if you want to say is no longer supported. But I think that would be what it looks like.
