Yeah, there's a link on it here somewhere. You just use a small jewelers screwdriver under the hood side to press in the little tab inside the connector.
If you're looking at the bulkhead connector under the hood, you can see the terminals inside; on the back of the flat side of that terminal end, there's a little tab that locks it in place...if you press that tab in with the tiny screwdriver, it'll allow you to pull the wires out one by one from the inside of the car.
Make sense?
