I am ready to rewire my '68 El Camino. The car is very basic, with most accessories stripped out. There is no radio, heater, AC, wipers, etc. Should I just use the universal 12-circuit harness? Do the universal harnesses still come with a way to deal with the hole in the firwall after removing the stock harness? I just want to make sure I make a good choice now, so I don't suffer later. Thanks

Come on guys, I know some of you must have some experience with this...

I am a Centech Wiring kind of guy. The GV18 is a easy to wire universal (based on the standard GM fuse panel) kit that is reasonably priced with high quality wires (including the correct sizes).

Go to http://www.centechwire.com/catalog/universal/gv18.shtml for more info. I have also used FActory Fit/American Autowire, Francis, and Painless BTW.
