Ian Crowe brings up a good point when he mentions using a clear plastic
conduit to enclose his "delicate" wiring to the tail.  If any of you
decide to use a conduit (of whatever material), I would reccomend the
inclusion of a "messanger".  
A "messanger" is simply a length of strong line or cord of a material
suitable to withstand the environment in which it is placed, and tied
off at each end of the tube with enough excess built in to facilitate
tying in to the wiring you are hoping to snake through the conduit in
the future.  The line must also be strong enough to withstand the
friction the pulling forces, and must be able to tie into the following
wire without creating a bulky knot that would inhibit the drawing
through of the new wires.
 "Kevcord" is a kevlar based  cordage available from any  chandlery or
"sailboat racing" catalogue. Its merrits are the thin section,  and
incredible strength.  Its pitfalls are instability to U.V. and cost. 
Co-latteral considerations are that the cordage will SAW through a
plastic conduit if tied tightly and then flexed, so leave some slack. 
Final note.  If you ever use the messanger to pull a new wire through, 
don't forget to include a new messanger line taped alonside the wire
being installed.(after all, you didn't expect to need it the 1st time,
right?)  P.S. This is a common practice in the routing of wiring on the
masts of racing boats which are commonly constructed of carbon fibre and
similar composites.
