The trick is knowing which de-pin tool to use for a particular connector.
If you buy a used donor - you can use that to figure out how to de-pin yours so you’re not learning on yours with limited access in the vehicle.

I’ve done it a lot and can usually come up with the right tool and process in 5-10 minutes for the 1st one. Subsequent pins only take seconds once you know how to release them.
Other option is find a good automotive electric shop - they will have tools and knowledge to re-pin it pretty quickly. They might have a source for obtaining new connector housing too?
Note: the $7 version of these tools are pretty cheesy (soft metal) they will get the job done once or twice but they eventually break / fatigue. The more expensive kits will have steel or titanium working surfaces.
