2016 RAM 3500 CANBUS Problem

+1 vote

Today I tried installing the Evo-All to a 2016 Ram 3500 diesel using the T-harness. I made it to step 7 and could not get past that. 

In step 7 it says “No key = Red” and “Key in= Red and blue”. Whenever i put the key in, the red and blue will stay on for a few seconds then only the blue will stay on. Is this supposed to happen?

I then put it into the RUN position but it will not flash rapidly. If I put it back into OFF, the blue will go back to solid.I checked the CANBUS wires multiple times and made sure they were at the right spot. I even switched them. In step 8 it says “ignition off= red” and “ignition on= red and blue off”. I dont see a red light after step 7 but the blue does turn off when the ignition is on.  One thing I did notice though was that the CAN-HIGH wire Grey/White Pin6 on the guide is a different color on my truck; its sort of a tan color but it is still pin 6. The yellow wire DOES match up. Would this have to do with anything?

I followed the intructions on how to test the CANBUS connection and ignition( The ignition is good but whenever I put it in RUN, the blue light will not flash so im sure its a CANBUS problem i just cannot figure out what it is. I also tried resetting the module and it did not work. I updated  it to the latest firmware and even dropped it down to the one it says on the guide but that did not work either. I also tried waiting in between the steps and no luck. Any help is appreciated.
