Will this fit without removing the bumper?

Yes. This mounts at the factory rocker points — you can access and install from inside the bed or from behind the tailgate depending on your truck's year. No bumper removal necessary.

Do I need a wiring harness adapter or does it plug straight in?

Connector type not specified in the product data. Test-fit the assembly against your existing harness before committing — most Ram tail lights use a common connector, but your model year may vary.
