What is this for?







Ford F150
1997 1998 1999 2000 2001 2002 2003
grey plug
under below dash
under below fuse panel
above parking brake
red/pink green/black wires
red with pink
green with black

 

It's for an option you don't have. I don't know for sure, but possibly power adjustable pedals. I know one of my trucks/Expys has one just like that with nothing connected.

 

Maybe from a dealer lot security chip?

I don't remember seeing that plug on mine. But I do have power pedals, so who knows

 

Those pedals look weird.

 

Clutch / Brake / Gas

 

Ha, I didn't notice the gas pedal.

 

That's for a trailer brake controller almost 100% positive

 

Nope, a TB controller has 7 wires, not just 2.

 

What the plug is for I am not sure but the wires goes to the speed sensor in the rear end.

 

Looks like a brake controller connector, but it's not in the stock place, nor would it have black electrical tape on it??

The BC on my 97 F150 was right next to the ODBII connector right above your right leg when sitting in the drivers seat..

Also, there would be a 'blue' wire going to the back of the truck. Even if you didn't have a 7 pin trailer connector, it would go to the rear as far as the spare tire.

Mitch, how can it be a TB controller with only 2 pins?

 

Here's the answer to your mystery its a plug in for a trailer brake controller I went outside and hooked it up tonight and took a picture for you non believers

Now unplug it and take a pic of the socket so we can see the pins, please.

 

Read the page here https://www.etrailer.com/faq-fbc.aspx this explains it all

 

That plug on the adapter does not look like it will fit in that socket.
