I am obviously confused by the two different parts shown above. when I look up blower motor resistor for the 1999 Nissan Quest online, I frequently see the second item shown as being the correct one for that model. Am I naming the part incorrectly or something, as there is no way that second part would fit into the same hole as what I pulled out does? It is a head scratcher for me, but I'll take both parts in to be looked at and try to get the correct part today. Just trying to figure out if it was just me or if I had somehow used the wrong name for the part and this one goes somewhere else on the system. The part was ordered as JA1399, but it lists for a 2000-2002 model and not the '99 model. It looks close to what I have pulled out from the car and when it comes in later, I'll see a bit better if it works or not. It has not come in just yet though.

It is indeed confusing, but may be something that the manufacturer changed production of on some '99 models for some reason. Compare the last photos to the one of my resistor above and you will see they are similar, but not 100% the same.
