I don't have the pictures handy, but we just id a full three-screen Skyview install, with remote radios, transponder, EMS, and ADS-B boxes. The remote units we mounted on a tray we built across the aircraft (not an RV) between the panel and the firewall. We had Stein build us the network cables to our length specifications. Many of the boxes are powered from the network bus, so they don't need any additional cables. The screens and a few other boxes need power and ground. The screens need to use a couple of serial lines - the supplied harnesses have all of the serial channels pre-wired - we just removed the ones we weren't using, and that really made the bundles similar.
I have built a fair number of panels from different company's equipment, and this was a pretty straightforward job.
