OK, here goes
this is from the cobalt manual showing the terminals and the 2 change over switches and lets us assume the turnout is set for the straight track ---
so the frog wire is connected to a C terminal and S1 & S2 to the track wires - so assume S2 goes to the straight rail & S1 to the curved rail & it works without shorting - if there is short reverse S1 & S2.
Now when you instal the next Cobalt whether face to face or back to back - C goes to Frog & S1 & S2 to track rails and you may have to reverse those 2 wires to stop a short.
One can draw the turnout in the straight though mode & add the contacts set to represent straight thru & draw connections accordingly but unless one is really up to that, I would connect one Cobalt at a time & test it before doing the next.
