Anyone have more details on this? I'm having this issue on my 2015 2500hd. I search for junction box and find no parts. The crazy thing is mine will start with the remote and not give any issues after. If we put it neutral sometimes it starts and sometimes it doesn't. When it doesn't start we put it back in park turn off and remove the key. Try again and it fires up. Any help on this junction box would be appreciated.
TIA
