Good but Upset
It did fit so I am happy with that, but the fact that before I ordered it, it didn't have some type of warning saying that I'd have to run a wire from my fuse box to my radio and there's not even enough wire for me to run it from my fuse box to my radio.

Metra® - Aftermarket Radio Wiring Harnes
Well fitting plug, secured it with solder sleeves, to stereo kit. Make a version where you can crimp your own wires and pins.

Works Fine for an Explorer 2002
Poorly explained how to connect considering you have two plugs from the radio. Needed to get someone to explain.
