As Stated above there's a switch under the steering column to cut off the dash panel and the easiest way to turn off the emblems is to just unplug the harness to them.
Understand before you screw these emblems up which wasn't posted in that other thread they cost almost $400.00 each to replace.
I didn't think I was going to like them but they do grow on you over time so my advice is to wait a few weeks before removing or cutting them off.
