Troubleshooting Curt Trailer Wiring Harness Not Active at All
Published 12/03/2021
Question:
How can we activate the circuit so that our wiring harness works? Currently the trailer lights will not work and all the connections seem accurate.

If you installed the Curt harness part # C76CR on your vehicle and it's acting like it's not active that would most likely indicate that you didn't run the red wire to the battery or even more likely the fuse didn't get installed in the fuse holder. I'd check those two things.
