So I looked all over the place and couldn't find a good explanation, and after a good amount of tinkering I figured it out. Please forgive me if I just didn't search hard enough.
To route the wires, loosen the two screws that hold the solenoid onto the body, then use your smallest allen key to stuff the wires beside the noid as far as possible. After you are done, tighten the noid back down... it should look like this:
You may have to try it once or twice to get it right. If it interferes with your trigger, you probably didn't stuff the wires down far enough, so pull them ALL out and start over (you really need to make sure the first one is as deep as possible, before stacking other wires on top of it).
This worked on my PM8, but I suspect it would work on any PM as the tolerances around the noid seem to be similar.
If anyone has any info about the part numbers, etc. for the connector, the emitter, and the receiver, I'd like to know those as well... Eyes for the PM8, especially, are getting kinda rare, so I'd like to have all the info posted up so people can make their own.
