Layout alterations....

...I have two roadblocks to installing it. First, I don't see a convenient hookup for a Peco switch. I can probably fake that.
I don't understand the wiring stuff that was provided. Especially the weird connector.

It would be a useful motor as I have 1 3/4" space between the roadbed and the L-girder right under it.

Depending on the particular Peco switch, you may have to fabricate a somewhat different wire than the one supplied.  The Peco switches that I have include an extension on the throw bar that may not be a good fit (too loose) for the supplied wire link.  Here's a photo...



While they're not among the ones needing to be powered, I'd cut off the extension and either create a longer wire or locate the motor proportionally closer to the switch.

The connector for the wiring threw me at first, too, but I did sorta figure it out...



The green block is for solid wire (not stranded), and all you need to do is strip the insulation off the ends of the wire, then push it into the proper holes - to power the motor, use the holes which match-up to the red and black wires on the other side of the plug device.  The bare prongs on the other side of the green connector block also correspond to the holes in the green block and to the respective wires on the other side.  I'm guessing that these are simply options to allow either plug-in or soldered-on wire connections.
The yellow thingies on the green block are releases for the wire installed in the the holes.  If you need to remove a wire from the block, simply press down on the yellow thingy for that particular wire.

While I'm going to use the plug-in feature to power one of the motors, I'll use the corresponding solder points to add jumpers to the second motor, at the same time reversing them, polarity-wise, so that when the circuit is energised, each turnout will operate in the same manner - either both as straight-through routes of their respective tracks or as a crossover, from one track to the other.  I think I have it figured out, but we'll see when I'm lying on my back under the layout, with a soldering iron in my hand.  
I probably should have done the soldering before installing the motors, but it took way too long to adjust the motors orientation to their respective turnouts, for optimum performance, so they're not coming out.
