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?
