I have a 2006 f-150 xlt and I have been having issues when I turn truck off and take key out the truck turns back on somewhat meaning radios on the dash is funky and won’t stay off like it should unless I hold brake down or unplug the plug on my passenger side fuse panel that’s above the fuses which has a pink outline around the plug in. What does that plug go to? Once it’s unplugged it’s as if the trucks off and normal . I’ve replaced the ignition and key already
