I purchased a 2016 Frontier SV. The truck does not come with a back up camera. I purchase a camera and an after market harness (AX-NIS-ADDCAM1 Aftermarket Back-up Camera to OEM Radio Harness) but I'm not getting a video signal to the OEM radio (#281859BK1A). I connected the power and ground to the back up light, but wondering if the RF video out is actually in the right location on the wiring harness. I would appreciate any troubleshooting or suggestions.
