What is this part?, Do I really need it? Options

[nsr-jamie]

Hello, got to work on my car a little this Saturday morning and replaced a switch, added one of Marks nice seals and some other smaller things...while I had the fuse box out under the dash I found this part. What is it? Is this the cause of my never ending clicking sound?? The car is always clicking with that sound you know when you turn on your hazards or pull the ebrake handle up...my car never stops clicking when its running...over the years I got use to it and eventually gave up but want to fix this annoying problem. It sounded like the clicking was coming from here. Do I really need this part? What would happen if I disconnent it and left the wires unattached (Don't want any fires, hazards or dangers)...is this switch or box or what ever its called faulty and the cause of my never ending clicking sound??

Here are the pictures, oh yes...the hazards are off and the ebrake all the way down and released and it still clicks even when the red light is not flashing in the fuel meter gauge.

Any help would be appreciated and thanks (IMG:style_emoticons/default/beerchug.gif) (IMG:style_emoticons/default/beerchug.gif) (IMG:style_emoticons/default/beerchug.gif)
