Installation of the aft wire harness actually started before the side skins were riveted to the bulkheads since the clearance through the #7 and #8 bulkheads at the top J-Channel is too tight once the side skins are riveted in place. I started the final installation by testing the continuity of each of the wires to ensure everything is in working order. All the wires checked out fine, so I started the final routing.
The wire harness is a little complicated (at least it is to me), and I had to study the drawings for awhile to ensure I understood which wire goes to each area of the aft fuselage and how the wires are routed. The first task was to route the C409P molex connector through the F-01410 bulkhead. There is just enough clearance below the top J-channel to fit the connector through, and then the wires can be move individually above the J-channel. The C409P connector then goes through the bushing in the F-01411 bulkhead, which has to be slit to allow the connector to fit through. There are 2 very long white wires (C1037 and C1036) that are attached to the C409P molex connector, and those actually route forward and out the front of the F-01406B bulkhead.
The wire harness has a thick white wire bundle labeled L1082 that also go through the F-01410 and F-01411 bulkheads along the same route as the C409P molex connector. The L1082 continues through the F-01412 bulkhead through a small hole just above the tail tie-down bracket.
The final 2 wires in the wire harness (P725 and TP724) are routed to the top of the forward side of the F-01410 bulkhead.
