Not sure how to get the links changed so that the photos show here but I'll work on it.
In the second pic, the larger gauge red insulated wires connect track braid from before and after the dead strips, providing track circuit continuity.
Three lanes; two dead strips, + and -, to each lane. The cut ends of each dead strip are joined by a copper electrical connector and a thin color coded wire from the TrackMate module is connected to each dead strip. Example: the green solid colored wire is connected to the positive braid of a lane while the green and white striped wire is connected to the negative braid of that lane. The TrackMate module supports four lanes.
Electrical tape (or a whole different set of connectors, lol) can be used to wrap and isolate the connections to prevent shorts across the + and - braid connections.
Many installations are much 'cleaner', but hopefully you'll get an idea of what's involved.
