I have a 03 dakota 3.9 club cab,

On the drivers side there is a box (I'm sure there is a name for it) behind the plastic panel down by the pedals. The bottom plug is for the lights, and such.

One my truck the plug is green from corosion so fog lights, left head light, and washer fluid don't work....

So what is the box called, and any ideas of how to get just that one plug?
any suggests would be great!!!

thanks
