Exclamation Help please. Engine idle mod....

So I was getting ready to do the engine idle mod on my 04 and i got to looking around. Found a switch next to/attached to the OBD port support/bracket. And a couple connections with nothing connected. anyone got a clue as to what they are. New to Fords, so if its something you think I should know, I would appreciate a kind response I'm hoping it's the engine idle mod already done for me, certainly hope its not evidence the truck has been "sprayed" or anything
BTW: they wires are still connected inside a wire loom and taped up. Not expecting anyone to know if it is the idle mod as I will only know when I try it out. Have to wait for the wife to wake up first(she works tonight). Just wanted to see if this could be something else or a switch found common in these trucks, like some sort of factory option.

Well, if the Lightblue/yellow stripe wire is not hooked to anything, then that switch isn't for high idle. Will be interesting to see if anyone knows what it could be used for.

Anyone?

found the blue/yellow stripe wire above the brake/brake release, it's still capped off and not connected to anything. the white/blue stripe wire is already in this mystery bundle and end is pinned into the plastic piece. as you can see, the two wires on this thing are both brown and out of this bundle there is a grey wire with black stripe that is crimped into a blue wire that comes from the direction of the steering wheel and ends in a socket/connection next to the rest of them.

my 1994 mustang gt convertible had a similar button, but you had to push it in while turning the key to start it. Some sorta anti theft thingamajig. obviously yours is something different.

Does your truck have a remote start or a security system?

Looks like a switch to put an aftermarket alarm in valet mode. But that just my best guess.

the harness looks like it plugs in to something, it's capped right now. button doesnt do anything that i notice. only came with factory "security" and fobs, no remote start. suppose the previous owner could of had an aftermarket alarm or remote start and just left the wired harness in the truck. but took the brains of the setup along with any fobs just for it. nothing acts or works out of the norm.

Well the reason that I asked is that I saw a scotch-lok on one of the wires on the ignition switch.

Yeah. Wasn't sure what they were called. Deffinately looks like an added in harness. Guessing I could just scotch loc the white with blue stripe power line in this bundle and be fine
