It comes with the full housing and 4-pin connector, so no need to Frankenstein old parts together.

Just unplug the old one, pop this in, and you’re back on the road.

App-autoparts makes this one, and they back it with a 1-year warranty.

It’s a direct fit — silver housing, clean pins, ready to go.

UPC not included, but the part numbers cross-reference with 74-9524-B, MA166-B, and a bunch of others.
