connection of Cab2 tmcc powermaster to fastrack

I used Lionel's Power Cable from the transformer into the powermaster (SKU: 6-12893) then from the powermaster I just used 16 gauge wire for a bus wire that I then connected to the track at various places by soldering to the tabs on the bottom of the fastrack.

If you don't want to solder or aren't proficient at it, you can also use these female 0.110 crimp connectors to slide onto the tabs under the Fastrack sections.

What about the single wire from the cab2 to the track
