I've loads of plan cable coloured cables, i'm looking at making a few wiring looms and i'm after a supplier for cables who supply
cables with colours and tracers etc on them.
Looked at rs and farnell (were i usually get my stuff)

search google for vehicle wiring products (VWP) they will have what you want.
VWP as ^^^ said will sell this by t he metre.
search web for blue beehive products - they sell wires by the reel - as you plan to make several looms, that may work out cheaper.
These guys are good too;
