Disconnecting Headlights

I have a rather dumb question. I am in the process of swapping out my old engine and forward light harness for one of the Evans wiring harnesses on my 69 Dart. My question is...is there any easy way to unplug the headlights so that I can pull the harness out of the front end or do I have to tear the grille assembly apart to get to the connectors? I looked from under the car and the top, but no obvious easy way stands out. Would greatly appreciate any ideas.
