I have a whirlpool washer, not sure about the year or anything, but I have it all connect except for a wire. Looks like a ground wire, not sure what to do about it? Help please.

Describe wire, what is it connected to?

If it is green, it is a ground wire and can be connected to the ground in the electrical receptacle or to a metal water pipe
