new to me 05 ford f150 fx4 supercab
there is a bunch of wires hanging down next to parking break peddle they all have plugs on them any idea what they are for?

 

They are handing loose with nothing plugged into them?

I've not seen anything like that in mine, do you have a pic? it could be from an alarm/remote start.

 

Someone posted that same question a while back. I think they came to the conclusion that the connectors were for reverse sensors.

 

My bad! You said parking brake pedal. I was thinking parking brake cable, along frame rail. Brain fart!!!

 

First. Look and see if there are some parts are missing those wires! If you don't see any go to a mechanic or ford and tell them to check out! My old man's excursion was the same, took it to ford and they fixed her up
