I searched - but cannot find out what this is supposed to do. Is it useless? If so, can it safely be removed in favor of a diff lock switch / lighting etc? Worth keeping? Keyless entry?

I believe it works with the keyless entry system. My LX didn't come with the fobs, or any of the chip keys, so it has never been usable in my truck. I didn't want to mess with the security system as I don't know if or how it has been bypassed, so I just taped over the light and plug and did exactly as you suggested and put my cdl switch there. I put the "security" cover plate right next to the drivers door in one of the empty spaces on the left of the dash. I figured what the heck, why not see if some dumb thieves might see the word security on the dash and not bust my windows. (Don't tell anyone!) It's a long shot, but makes for one less blank cover too:coffeedrink:
Will I have issues with not having a chip key?
