Wire bundle number and location

Could you please confirm the bundle designation assigned to the conductors identified by the red rectangle and arrow in the attached 737-300 wiring diagram, and indicate the location through which these conductors are routed? 
  
     
 

I have never found a reference as to exact locations of wire runs in the aircraft.

We've always hand traced wires with the use of a Fox/Hound device.

I had to delete your post with the whole chapter 91 PDF. I cannot post complete images of technical references on the site.

With reference to the file I forwarded (email) a few minutes ago, could you advise how the chart may be utilised for wire-tracing purposes?

Again, I wish I could help with your question.

The charts you sent show wire bundle runs but, they do not show actual location on the aircraft.

If a detail of the runs is needed, the only way I could see it being done is when an aircraft is in heavy check will the wall and ceilings removed.

I'm sure Boeing has engineering charts that show the manufacturing locations of each run. I have never seen anything like this in their line maintenance manuals.

What eludes me is the discrepancy in the wire-bundle numbering: in the chart, the bundle numbers consist of four characters, whereas in the Wire List tables they consist of five characters, according to the file I just dispatched by email a few moments ago.
