I'm guessing I need around 12 foot of Red and maybe 3 foot of Yellow.  I'd have to really check to see if my lengths are correct, but as you can see,  I need very little wire.  If this doesn't work, where could I buy the needed wire in any other color including clear?

I got the idea knowing Drake used the center conductor of RG-8U for their high voltage leads in the L4 and L-7 amps.  (RG-8/U center conductor would just be too large in diameter for my needs.

   Household wire (like AWG 14 THHN is only good for 600 Volts.  (you could get scraps from 
electricians)

   I would tend use automotive or hookup wire and add hV bushings (or other insulation) where the 
wire was exposed to ground or other potentials.  I would not use hV wire everywhere, just where is 
it needed.
