These two photos show some of the wiring ... please note that the connection blocks and some of the wires haven't yet been mounted in place under the module as of yet but this gives you a good idea of how the module is hooked up. I have planned locations for power packs when using the module at home, one of which you can see in the left-hand photo. The right photo shows under the end module to see the wiring and how the modules are held together, the clamps are temporary until I've installed a support angle brace to hold up the end module so that it won't droop.
The wiring harnesses shown in these photos were acquired from Z-Bend Track ... I'm using one FM-1 and two EM-1 harnesses for this set-up with the FM-1 harness extended somewhat to help me deal with getting it around the canyon. To allow me to operate the layout at home, I'll also acquired some power feed harnesses as well and I've wired up the accessory power even though I've not come up with any features to hook up to that power line as of yet.
