I have a v1.4 Xbox and I followed the trace corrosion repair thread. I saw that trace A which is in the picture was bad and I tried to run a wire from the via, but it was too difficult.

I decided to instead run a wire from the top side of the board to the end of the trace at the circular pad A. So, I wired it to the right side of the bottom signal resistor that's highlighted in red in the P/E continuity trace linked picture. However, I just now noticed that maybe the wire should've been soldered to the left side that's highlighted in pink.
It seems to go on and off correctly, but I'm worried maybe I'm bypassing the resistor because of the way I soldered it in.
