Hi all,

I've replaced my factory REF radio with a single DIN android head unit in my 2008 Ram 1500 ST Quad Cab. I've used a CRUX SOOR-26 radio replacement interface. The radio works fine in the truck, but there are CAN BUS connections on the radio (see the attached diagram). I was wondering If I connect these to the CAN-B lines at the radio connector pins 5 & 6, or do I need to connect to the CAN-C at the OBD port? Should I even attempt to connect this to the CAN BUS might be an even better question. The head unit is supposed to support steering wheel controls and other features. I though I might see what it can do.
Here's the ebay add https://www.ebay.com/itm/Single-DIN-...53.m2749.l2649

Thanks for any help you can give.
