There were 2 wires (instrument/switch) that were in the left-most bay where the E-buss is mounted that went to the main buss. I had originally routed these wires on the cabin side of the subpanel and through one of the lightening holes in the left support rib. These 2 wires were unsupported and took a rather abrupt turn after passing through the lightening hold in order to connect to the main buss. I decided to re-route these 2 wires along the main wiring run, which meant bringing them through the sub-panel and running them along the forward side of the subpanel and then back through the sub-panel again to the main buss. The run is a bit longer now but the wires are fully supported and this has cleaned up the left bay where I have the E-buss located,
Much cleaner - wires routed from instrument/switche through and then forward of subpanel
and then back through the sub-panel to the main buss
