Mike, I'd like to be able to help you, but I have no experience with DCS wiring. Hopefully, this post will bump up your topic.
I'm guessing you already know that with DCS that there's more to consider compared to wiring other command control systems, and it's why you're asking for help. The DCS Companion Book by Barry Broskowitz is often mentioned as the main go to resource.
For this topic to get more attention, you might consider Editing the Topic Title to indicate that you're Looking for Help with DCS Layout wiring. I hope this is at least somewhat helpful.
