I can share photos of my 7 as well, but basically I ran the wiring down the firewall, under the cover on the forward floor (parallel to the fuel run), through the spar (at Van's approved hole locations) and along the edge of the tunnel with the pushrod to the bellcrank in the tail cone. Same routing as the tail lighting runs. Not too many wires, it was an easy run.
