Location for the turn signal flasher on a 2008 Chevy suburban

Doesn’t have one, the sound is generated by the BCM, you need to wire in resistors to make the turn signals work. I had to do the same thing on my Yukon and my Silverado. As they run hot make sure they are not close to anything plastic and they are secured to something metal as they need it for a heat sink.
