A friend needs some assistance on a 12v wiring task. I was going to do it for him, but have really locked myself down by suffering a slipped disc.

So I said I would draw it out or him, but cannot find a computer package that will allow me to draw coloured wires between connectors, and I don't have anything that will do brown or yellow if I was to it do it by hand.

Anyone got a suggestion ?

Thanks
Rob
