2008 w204 thermostat issue

Hi everyone i have an issue with an installation I just did. I recently replaced the thermostat on my c300 and I might have damaged the wiring harness with the electrical connector that attaches to the thermostat. So right now since installation I'm getting no heat in cabin and engine fan won't come on. I was hoping to replace with a pigtail but can't seem to find anything that looks similar. Does anybody have any ideas or suggestions. ? I appreciate your responses

Yours is the same as mine, 204.081.

I'll post the parts diagram for the connector.

Ok thank you. Looks like I'll have to build it with molex pins. I cross referenced the part number you posted and found one that was pre-made on ebay. Ill post when I've installed if it worked. Thanks again
