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.
