I have great news, but first some context. Having driven my car without it's bumper some distance, the male side marker connector that is attached to the engine wiring harness was completely destroyed, leaving only wires with their connector sockets and weatherproofing seals. The good news is I have found, purchased, and verified the fitment of a replacement male connector for a couple dollars + shipping.
Link to where I purchased my replacements:

The connector is a
Sumitomo MT-2S-1 with
SUMI.A-SKT1 sockets and
SUMI-SL1 seals. Those are the options I chose on the website that match the sockets and seals that I had remaining on my wires. I'm not sure if those socket and seal part IDs correlate to Sumitomo part numbers.
The actual Sumitomo OEM P/N for the connector: 6180-2181
Happy fixing!
