I have an electric e-cutout on my 5.9. Just before the muffler but infront of the O2 sensor. Works great. welded it up and wired it to my amp for my subs to get power. It's LOUD. To be honest, it shook loose some of the bolts hidden somewhere in my bed so it rattles now sometimes. I'll take a new video for you tomorrow but this is what i have.
