M2grimm. I bought the camera reroute harness from infotainment.com. I have a 2014 R2 radio (1C6RR7KTXES343642). It’s in a 2013 ram1500. Anyway Everything works great. New auto dim mirror bezel and factory harness to passenger firewall. Awesome. Then I install the reroute kit infotainment sent me. Correctly install pass through with rca video cable splice at firewall. I then install harness they gave me to factory radio plug. Plug rca cable in and start truck. Put truck in reverse, and no change on video screen. Still has radio displayed. Nothing. So I call the tech and now they think it’s something with my firmware? I don’t think they sent me right harness. I have extra four pin connector just hanging and has red, green, black and orange wire. Looks like a power plug to me. But it is not supposed to get plugged in so they say. I just need a 3 pin jumper from the fire wall block to the back of the original radio multipin connector. I am so confused and frustrated and confused. This should not be this difficult. Any suggestions?
