Does anyone know where I can buy a wiring harness to run the 3rd brake light on my camper? Looking for the pigtail type that I can just plug inline with my existing connectors so I don’t have to cut into the factory harness.

Im seeing a few options for 2 wire set up but I’m looking to get a 3 wire set up to run both brake lights and running lights.

Thanks in advance!
