Expert Reply:
The correct brake controller install harness for the Curt Spectrum part # C51170 to install in your 2019 Chevy Suburban is actually the part # C51451. Most likely this was a typo though and that is what you have.
This is a proportional controller though so it isn't going to put out braking power unless it senses movement.
