Horn..

I just did the replacement of my horn with the bad boy. I to have the 08 Sierra, I'm assuming mine was factory bought the truck used. But location was actually on drivers side in front of the windshield washer fluid container..was easier to mount new horn with removing container. Needed to cut plug off the factory wiring and replace with two female spade electrical connection to connect to new bad boy horn. Hope this helps.,
