Wires powering the Upper console and Rear (wire ran for later use, no fuse installed at present) travel up the A pillar. Notice the wire to the Upper console run up the pillar and behind the headliner while the wire to the Rear (cargo area) runs inside the A pillar. An existing fastener was used for the relay ground (green wire) this only grounds the relay, not any of the other circuits so the wire can be small.
