Yep, I congratulate myself for having the only 2001 Tracker on this planet that has no trailer wire stub-out in the harness. I know where it's supposed to be (inside the left-rear panel). However, I removed the entire panel and the only stub-out was a 6-pin plug for an additional speaker. The tail light harness went straight to the light with nothing coming off of it. Oh well, thanks for trying to help guys (and gals). I guess it's back to splicing wires.
