Gee, I hate to be the one to say, "run each wire your self" but it inexpensive and it gives you what you want. I ran a size bigger for each wire to eliminate "size " problems. I planned the wiring in stages ( this makes it easier ) and I soldered each connection then covered it with glue imbedded shrink tubing.
If you do the rear first, then the front, then the engine compartment and finally the cockpit, you can have this all done for about $100. That's using good materials - no "el cheapo" brand materials.
If you decide to do this, find out what you need to pass inspection. Neutral safety switches are not manditory here, but I would put on in.
Just my $0.39 worth.
