Air diffuser

I replaced the air diffuser (Whirlpool part #w10899382) due to a knocking sound coming from it. That took care of the problem though I’m not sure I did everything properly.
My question is there were two identical wires,one short and one longer, that look like sensors that I wasn’t careful enough to pay attention where they go when I took out the old one. The long one I believe was taped to the diffuser
The short one is below the part that goes into the freezer and the long one is connected to wire connection that plugs into the diffuser.
Can someone give me advice on where they go.
