Ah gotcha.
This will be on the lower end of $1,000 from start to finish for a diy.

And some type of OBD link that supports AlphaOBD I personally went with OBDLinkMX+ but there are other potentially cheaper options.
Word of warning when you go to replace the tail light harnesses with the "Jumper Wiring" I ended up breaking the old harness clip on the passenger side due to body metal being in the way and how the tail light comes off. If I need to remove the passenger tail light again I'll end up having to break the new harness. You may not run into that issue, but just so you are aware...
