You must have been using some type of bypass harness to enable the codes, correct? The alfa tool shouldn't be able to connect to the truck to enable the codes without one. It would appear that whatever security bypass harness you were using worked because the tool was able to connect to the truck to enable the controls to come up on the screen. Once the codes are enabled the security bypass harness is no longer needed. One thing I did notice in your picture was that your heated seat soft keys were much larger on the screen than your vented soft keys. When I had my UAS/UAQ radio in my truck which is what you have my keys were the same size. Doubt that it makes any difference but thought I would mention it. It may be because you don't have the heated wheel enabled so the soft keys are configured differently. The fact that you cannot connect to the HSM module is what makes me believe you could have an issue with the CAN connection or the wiring that you installed. The fact that the buttons don't turn on at all could be related to that but I have never tried pushing the switch panel buttons without being connected to the CAN so I can't say for sure. I do know in many cases when people have done this mod and the wiring is correct but all of the codes are not entered correctly the buttons will usually turn on for a few seconds and then turn off. Another thing to note is the 2013 trucks take a different switch panel but they look identical to the 2014 to 2018. To verify your switch panel is correct just use the other buttons like the tow/haul ect. If they work your switch panel should be the correct one. You could also have a problem with not getting power to the two pink wires with yellow stripe when the truck is on (ignition on run). It's obviously hard to trouble shoot when I can't physically see the harness you installed but if I had to bet I would say that's the first place you should troubleshoot. I would double check that all the correct codes are enabled with the tool and verify you HSM module is still attached to the seat and all the connectors that run to it are attached because that won't take long to do and then focus on the harness from there.

I finally had time to look into your suggestions and right off the hope I found I was not getting key on power, checked the trigger to my relay and I had a poor connection so now I guess you have a few more questions answered
Yes you can use 2014 seats in a 2018 truck, all modules still communicate
Your wiring instructions from post 1 work on a 2018
The Z bypass module works for communicating to all systems (but I would still rather pay less money for the bypass harness from Deere Guy)
Now all that's left to do is find a heated steering wheel but that will have to wait till next winter
Thank you for developing this mod and still supporting the form
The Canadian winters will be much nicer
