On the fuse block of my Wagoneer, there is a large blue box 2.5 inches wide by 2.5 inches long with 7 terminals that plugs into the bottom slots. It has a computer chip and circuit board inside of it. Three of the terminals are rusted away and it needs to be replaced. My local parts store doesn't have it and doesn't know what it is. And it's not identified in my repair manual. What is it? What does it do? And how important is it to the function of the car? I would greatly appreciate any help you could give me.
Thank You
