That may be possible, I honestly haven't tried.

What i did originally was bought a wire crimp (?) ... Um, this thing...


And just laid the tail light wire into it and then the line going to the relay from the tail light. Pinch it together and it breaks through the plastic cover and connects the two lines. However, i decided later I wanted a more permanent solution, so stripped the plastic cover off a small segment of the tail light wire, stripped a bit of plastic off the relay wire and wrapped it around the tail light wire, and soldered the two together, then covered the connection with heat shrink.

The only thing i could see going wrong if you power the tail lights through the relay is if the relay goes bad, you loose your tail lights.
