I'd have to look through my notes, but I used the EP27 when I installed savvy tails and the hazards didn't work on my 04. Problem is that I don't remember which relay actually did...The EP27 (5 pin flasher) is for 2001-2006 TJ/LJ and the EP26 (4 pin flasher) is for 1997-2000. This does matter and makes a difference.
Edit:. I was able to look it up at auto zone. I used a Novita LM470. Dumb thing was a pricy bugger at 30 dollars.
