2018 Ram 1500 gauges don’t work

Post by MoparFin »

I have a 2018 Ram 1500, 5” stock radio with uConnect, backup camera.

Purchased ch3 ver 1.80 harness to install my Pioneer DMH-2660NEX. Everything works as it should except the gauges. I can’t figure out where to put harness at junction. Do both connections need plugged in?

The harness that we show going to the CAN junction connector under the driver side dash will plug into the green junction block with the while 2 pin connectors. Simply remove any of the 2 pin connectors from the block, plug our connector into the block, and plug the connector you removed initially into the other connector in our harness. Be sure to connect the small black 2 pin connector in that harness to the black 2 pin shown in the diagram and not the red 2 pin.

What does the LED on the RR do when the vehicle is running and the radio is powered up? What message is displayed on the radio when you go to the gauge screen?

That either means when the RR was flashed, the wrong radio model number or serial number was used, or the 4 pin black data cable that connects the RR to the radio was plugged into the wrong spot on the RR, or it came disconnected from the RR or the radio.
