Hy JD Bob, I'm a retired mechanic, not a computer guy, but I have never seen, or heard of a website that gives the lengths of each wire and the type of terminals used. As for the colours, they are in the shop manual. As to the colours, I had to make a harness from scratch for a big Diamond T, and when I went to order wire I found out you can't buy all the colours you want over the counter, hope that helps.
