You can make your own harness with little trouble and cost. I made this one for a 74 VW Thing before it got rear ended and pretty well shut the whole job down. This was going to be for a radio setup. It is plastic coated, stranded, "pull" wire as would be used in steel conduits, from Home Depot. I use 14 and 10 ga wires. I also went with just one color but you can use all the colors you like. You just have to buy more wire though. Use the peel off numbers in the electrical section that electricians use to mark wires on the job. Get some REAL heat shrink tubing, not the cheap PVC stuff from Radio Shack. Take the plastic connector insulators off the lugs and crimp without them. You get a better job and then cover with heat shrink. Lokks absolutely professional and is bulletproof, even water proof if you do the heat shrink good enough. this is the same wire that Painless uses. It is everything proof and temp proof to 120 degrees C I think (been a while since I thought about that one). You may have to buy a fuse block to start with and build off that.
