Connector / Pigtail Online Retailer
I stumbled on something interesting:
Looked like a wide selection, interesting maybe useful. Some manufacturers are exceedingly unhelpful about providing connectors, the expectation is that you buy a harness. Some dealers will warranty a harness and keep it laying around just to prune it to fix a few cars. I know over the years I saved a few cars with old harnesses.
These don't look cheap but anything is cheaper than a complete harness. Especially when that harness needs to be fabricated in Germany for two weeks and shipped across the Atlantic.
I have used this company many times. They are great! Excellent customer service and they verify the connector through picture message which works great as well. True, they aren't cheap, but when compared to dealers that do stock the connectors, they are comparable in price.
