Hey Richard, thanks for reaching out!

The etrailer Trailer Hitch Receiver # e36YR is my hitch recommendation for your 2021 Chevy Blazer because of the matte black finish. This finish makes it more durable than the classic glossy black finish we see from other hitch brands.

Then for wiring, the Curt T-Connector # C56325 is your best option, and I recommend securing it near the hitch receiver with the mounting brackets # 18144 and # C83DR.

It looks like you'll be towing with your Blazer - what kind of trailer are you towing, and do you already have a ball mount?

Hey Richard, did the hitch and wiring harness work out for your Blazer? I'm curious to know how it all came together, as it could help others looking to set up their Blazer for towing.
