I just received my C51170. Plugged the harness into the vehicle, put the rest together and plugged together......nothing! No lights Unplugged, went through it again, still nothing. Suggestions?

The Curt Spectrum Trailer Brake Controller - 1 to 4 Axles - Proportional - Dash Mount # C51170 along with the Curt wiring adapter # C51392 is a confirmed fit for 2019 Honda Ridgeline according to the manufacturer. You can use a circuit tester like # PTW2992 to check for the 12V power on that harness. If you have power you should have lights unless there is a connection issue. Look for bent pins reconnect.

Then in engine compartment look at fuse box B located by the brake fluid reservoir. Check fuses 3, 6, , 9, and 11. One of these may have a connection to the brake controller power. If not, you will need to try to physically trace that wire or bypass it using kit # 5506 to hardwire the brake controller to your 7-way.
