The harness is $600!? WTF? Can't you just splice into the other brake light. What a rip-off.

You can say that again, thank god I wasn't interested in the "upgrade", no doubt that's full retail+. I actually wasn't too surprised since I was told that one piece license light wiring harness (for the factory tire carrier) was something like $100.
I'm sure it can be spliced into the existing brake light circuit or from the trailer harness, the $600 is probably a full harness for all the rear lighting.
