Question About Trailer Wiring Connector

[sockwell]

I pulled a brain fart and ruined a couple of the pins in the 4 pin side of my trucks trailer wiring connector. The truck has the combination 7 pin/4 pin connector. I ordered a replacement from the local dealer and tried to put it in today.

I removed the body of the connector and unplugged it from the wiring harness. Unlike most connectors I've seen, this connector has a couple of small individual pieces that lock the wiring harness plug to the connector. Does anyone have, or know where I can look up, a picture of how these pieces fit together? I'm usually pretty meticulous in looking at assemblies before I take them apart. In this case, I didn't relaize the two small parts were not made onto either of the plug's mating halves.

Thanks for any help you can give.
