Good evening, fellow Ford Members,

My name is Dan and I am having trouble figuring out where to connect a pigtail to and where do I connect the third wire of a new fuel pump cutoff switch I received as oppose to the 2-cavity fuel cutoff switch that originally came on my 2005 Ford Expedition 5.4L XLT. Please see attached photos and please help me somebody!

Are you talking about the inertia sw ?

Why are you trying to change the switch that came with the vehicle?

I ask these questions so we have some idea of what we want to accomplish.

 

Not the inertia switch,but the connector itself Hanky. All the auto parts store only had the 3-cavity connector, so what I did is remove the extra wire from it to be able to splice it to the original one so I think I will be good there. It's just now figuring out where the unknown pigtail connects to. The part number details says it's either connects to a rear air suspension (RAS) switch or a fog light switch, but it's in the rear left and I don't see where it connects to at all.

 

I still wonder what brought you to that spot.

A little FYI,
If you purchase from a Ford dealership parts dept, , you don't usually have these type problems.

If you purchase from just any auto parts store, you could wind up with "Fits All;" parts and the problems that come with it.


If you go to a dealership, they usually need your VIN because all vehicles are nowhere near the same.

Can we ask what brought you to this problem ?
