The best/cheapest place I’ve found for the Volvo female connectors is Aliexpress. For example,

They only seem to do the two-pin housings, but it’s rare for the original plastic housing to be beyond reuse. I prefer the pre-made tails which you can then join onto the original cable with heat-shrink crimp butt connectors.
Aliexpress send products direct from China and elsewhere so delivery can take several weeks.
