2012 Jeep Wrangler Unlimited Sahara turn signal relay location

"Hi Michael and Tracy,

This model doesn't have a turn signal relay. The computer tells the lamps to flash. If you have a fast flash, that's an indicator that you have a bad bulb.

Cheers!"

The only way to take of fast flash is add a resistor. Basically fooling the computer into believing there is a traditional bulb attached. Fairly cheap poison spyder has them for like 20. Just be careful they get hot so mount out of the way of plastic and fabric. Only the rear turn signals need the resistor the fronts on my 2010 never caused fast flash.
