Joining, in my opinion, is best done with full scab boards for long term racing surface stability, unless the track is full box construction.
You can get cabinet bolts and use boards underneath to pull everything together, but screwing it all down is the best. Even to take it apart....rejoin the same way.
So the wiring is pretty easy. As Slothead mentioned, you can do the banana plugs and color code them per lane. The other option is a 3 or 4 up male/female connector where you wire both sides and then just plug them in. I did that on my garage track (a 3 lane track on 2 4x8 sheets) and it worked perfectly with copper tape. Put the tongue/groove joints together, clamp it tight, then plug in the two connector pairs and the track was ready. Easy peasy.
