I'm doing the same as Kip's41... I am rewiring things myself with spools of wire. Since what we're doing is similar to what you're doing (only we don't have the diagram or the numbers) I think that we can help you out.
Alan Horvath might pop in (he's one of the moderators) and throw in his two cents. He's done a harness kit rewire job and may be more helpful to your specific frustrations than Kip or I. He's got a write up that might interest you. It can be found
here If you have some specific questions (e.g. "I have a six gauge wire. Where does it go?") Kip and I can probably help you out.
