Do I use one auto reverser and connectthe two track feeds with a parallel power strip and the two reverser feeds with another parrellel power strip or do I use two auto reversers?
Also, do the insulators upper left and lower right get paired to the same circuit and lower left and upper right on another circuit?
I am asking because I read one person stated only one auto reverser per lfigure 8 and an article I read stated two auto reversers, one for each crossing section.
It’s all in how you choose to gap and wire the reversing section. There is often more than one way to do it. The key is to completely isolate the reversing section from the rest of the layout.
In my diagram, one auto-reverser is all that is necessary because only one reversing section would be created. You would never use more than one auto-reverser to control a reversing section.
The four pairs of black dots in my diagram represent “gaps”, either plastic rail joiners or physical cuts in the rail to disrupt electrical connectivity. By placing those four pairs of gaps, the figure 8 would be completely isolated from the rest of the layout. The figure 8 becomes the reversing section.
When wiring this track configuration, power comes from the main bus and connects to the input side of the AR-1. You can place as many feeders as you want inside the reversing section, but all of those feeders should connect to the output side of the AR-1, not back to the main bus. Any feeders outside of the reversing section should be connected to the main bus, not to the AR-1.
Forget about parallel power strips. There is no need for them.
As far as “insulators” are concerned, remember, those black dots represent “gaps”. Plastic rail joiners are often called insulators. If you cut physical gaps through the rails, you could fill those gaps with epoxy or styrene strips, or some thing,
Here is the wiring protocol that I am suggesting.
Be sure to follow the color coding so that you don’t create a short by cross-wiring.
Please forgive the spaghetti-like mess.
That is how my underlayout wiring looks. [:(]

Thanks Rich for all the help. Very much appreciate. I received quite the DCC education in the thread and everything worked out well.
Glad to hear that you are up and running. Congrats.

Okay, I am sure it is in a thread but when I search for Double Crossover DCC Wiring all I find is threads on the prebuilt Walthers or Shonia Double Crossovers.
Can someone point me to a thread or recourse on how to DCC WIre a Double crossovers using four #6 Atlas Turnouts and an Atlas 19 Degree Crossing?
I did not want to start are new thread and I have spent considerable time searching for this info. A push in the right direction would be much appreciated.
As long as both parallel tracks are the same polarity (i.e., no reverse polarity involved), there is no special wiring. The only concern would be to include adequate feeders among all four turnouts and the crossing.

ThanksRich. When I looked at it I was thinking the same thing, but it just seemed to easy so I thought I was missing something.
Track A and Track B both have the same polarity. Outside rail is blue, inside rail is red on both track if I were to draw a diagram. My single crossovers worked fine, I just decided to make them a double crossover.
I have a Walthers Shinohara double crossover on my layout wired the same way. The wiring will be no different in the case of four Atlas turnouts connected by a crossing to form a double crossover.
