Yeah it's possible I used different wires. I'd have to pop off the panels to see which ones I used. I know one of them was way up by the headrest for the rear right seat that one was a PITA to get to because there wasn't much slack in the line. The others I got from the right side and 1 from the left.I don't see how that makes a difference - Maybe you pulled the marker and turn signals from different source wires than I did, but using the relay pack versus directly wiring it shouldn't matter, that is only a means of separating the two lighting systems from possibly overloading each other.
Where did you pull the lighting signals from? I got mine from the harness on the back of the lights on each side, I'd have to pull the covers to see what the colors are. I was following the video tutorial that was posted elsewhere here on TMC.
I don't always pull the exact same trailer - witness the three different ones I pictured above, and Uhaul frequently has old incandescent lighting rather than LED b/c they use their equipment to destruction (which can take a LOOOOOOOONG time for their trailers). So the relay pack was a personal requirement to protect the car's electronics from any trailer funny business that might happen.
And yeah in your case it makes sense to have it wired up to not splice but I still dono if it would be a problem it's just something I hypothesized when I was doing it since LED draw like 0.2A vs an incandescent trailer light drawing like 2A so I figured since the car wasn't designed to have that much current draw it might pop a fuse or start throwing lots of errors but I dono if it actually would.
