955i wiring diagram

[Arkansas Traveler]

I have lost power to my rear tail light.  The brake light works but there is no power to the yellow/silver dot wire to the tail light.  I'm checking for power at the connector under the rear rack where it changes from yellow/silver to red.  The wire disappears into the wiring harness and I'm not sure where to check for continuity.  I replaced the 5 amp fuse in the fuse block and have power on both sides of the fuse. 

If anyone has a wiring diagram or can tell me where the junctions for the yellow/silver tail light wire are, I would be very appreciative.

Thanks for your help.

It appears my file is too large to attach, PM me your email and I'll forward the diagram to you.
