Hazard / Popup Wiring Connector

I'm working on a DIY hazard and popup button project, but I'm having no luck finding a plug and play harness/connector. My Google game is usually pretty strong, but this one has me stumped. I'm not familiar with the correct terminology (and can't even find a resource to help me learn the terminology) and image searches are only not getting me far enough. Here's a picture of the connector attached to the stock button housing .

I would think that this is a standard shape / configuration, and fairly easy to get since there are so many off the shelf products similar to what I want to do, but I don't know what terms to use to find it. Image search results of similar connectors aren't helping me.

Are there any electrical gurus here that can help me find this?

Thanks.

Nearest I can find are Sumitomo's Unsealed HD090 and MT series connectors. That looks similar to the radio harness plug, so it might be worth asking Metra what the connector series and type on the radio harness adapter is.
