Here's what the doorswitch looks like:
Here's where it plugs in:
The soda can's in the background for scale. It's toward the back of the door to the bottom corner. Unplug the wiring harness & give it a ccw twist. The new one's easy to plug in, but kinda a pain to twist back in. Shouldn't be hard, probably take about 1/2hr. to do. Note on the bottom pic of the switch pin's location, there's a tongue where it locks into it's mounting hole
