Fuel Filter Housing Electrical Connection?

I was replacing my fuel filter this weekend ...(first time) and noticed on the top of the housing that there is a red and black wire coming from a split loom to the top of the housing. the black wire was landed on the screw of the primer button.. the red has a rubber boot on it like a connection of some sort. it is just hanging loose. not connected to anything. i noticed a spot on the housing that looks like it could plug into...but i want to know what it is for?

i found a pic online of what im talking about...
can someone tell me what this is for? sorry if stupid question...

I think that was the problem, this morning I was taking of to work and it wouldnt start, I blamed it on the weather when it was a very rare 35 degrees out here in south texas. since I just got the truck on friday wasnt to sure what it was and after inspecting the fuel filter connection tge little brass tab inside us all skooshed up. How can I order it or what is rhe correct name for it? Thank you very much for the quick reply.
