Hey man I see no one has replied to you, but I’d highly recommend switching to the hardwire setup. When I did a RT flash with the splitter, something caused my radio to mess up really bad. But since I’ve switched there are no more issues.

I got my diodes yesterday so I am hoping to get to it this weekend, I will post pics if it works
So.... I wired this per the directions in the 2015 installation guide, and I have nothing. Getting to the plugs on whatever box they are plugged into is a pain in the a$$. I ended up removing the drivers seat as I thought it would be easier to lay down and access the wiring. The instructions for the "component" removal are wrong. If you have the Alpine audio system, I think it is the amplifier that blocks access to the harness / plugs and the amp does not come apart from the bracket, the bracket and amp come out as a unit, removing the amp from the bracket per the instructions is impossible. All the wiring colors matched and as the instructions state there "may" be two violet/grey wires on the blue plug. On mine there are 2 violet / grey wires. I taped into one of them, picked the most difficult wire to get to and took my 50/50 chance that it was the right one. Got all the wiring done, spliced 4 wires with diodes and connected the drivers side wires together and the passenger side wires together then connected them to the AMP wires (2 each) and nothing.
The OBD plug has a circuit board inside (see pic below) so maybe this was never designed to be hard wired. @beans20 you mention a new controller is needed, maybe that is why mine does not work. Did they replace the box under the hood? I am sending an email to AMP Research next.
I converted my Amp boards from the OBD plug to hard wire on my 2014. Cost me about $5 in diodes, wire, connectors,and solder. Didn’t have to buy anything from Amp.
If you are a 13 or later the wires are under the dash and not at the fuse box. Fat hands do make getting at the wires under the dash a pain.

That is what I thought and at the worse I thought the rear drives door may not work if I choose the wrong violet / grey wire. The diodes allow the signal to flow to the controller and prevent it from back feeding to the truck. I wired the two drivers side wires together and the passenger side wires together (after the diodes) and connected them to the two wires to the controller.
Here is my wiring diagram....
I sent this to AMP Research also for their review, but does anyone see anything wrong here?
That is exactly what I did. Should be two purple wires off the Amp module. One for drivers side and the other for passenger side. I used some jumpers to make sure I had the correct wires before splicing.
Also make sure you put the diodes in the correct way. I might have had to redo one

@BrentM the controller under the hood is designed specifically for the Plug-N-Play setup, so they sent me the one correct for the hardwire setup. Mine works perfectly now! I’m not good with diodes and what not so I just bought the harness, and they warranties the controller under the hood.
Thanks @beans20 and @Wisenheimer that is what I was afraid of, I reconnected the OBD plug to the controller and still nothing. Hope I have not fried the controller. I will wait until tomorrow to see if Chris at AMP gets back to me.
