Post Is a harness really necessary?

Alright, I've been reading these posts about wiring harnesses and such, but I was wondering if I can just rip out my old one and run new wiring? It seems to me that wire is very inexpensive compared to a whole new rig-up. Also, I have a wiring diagram, but no experience. Would it still be better to just get a harness?
Thanks!

If you have the time, patience, and knowledge it can be done. Thats the way we did it back in the 60s. But I'll never do it again, not when I can buy a complete Harness with fuse block and instructions for $200. How much is your time worth? How about peace of mind? Knowing its right the first time or at least 99.9% of the time.

A harness is not needed at all. at times they do make life easier if you are running more than the basics. On el Poncherello I have the bare bones. tag,tail,brake,headlights,guages,alt,battery, starter, and ignition. I have 1 main fuse, then a 4 pin homemade fuse panel. all I can say is this use different color wires, mark them all. and make a map so a year or so down the road when you need to get back in there, youll know what your looking at!

You are going to get a lot of opinions on this one and they are just that - opinions. Don't listen to Draglinkscc - that guy is Superman and does stuff mere mortals can't!!!! He built his whole car in a week.

I have done it both ways. What I found is that a complete ground-up rewire ended up costing a lot more than a harness, took the better part of a month to do compared to an evening for a harness and I subsequently had constant little electrical bugs popping up (shorts, open circuits, bad connections, burned components, etc.). Also, parts store wire quality is much inferior to that used in a harness and they don't have near enough colors and sizes to do a proper job. If you find a store with good wire in proper size and color, you most definitely will pay much more to put together your own system.

In short, it is my experience that it is false economy to not use a harness.

HARNESS AINT REQUIRED. BUT A FUSE BOX, (PANEL) IS. A NEW ONE'S $100. NEW WIRES, @$100. ALL NEW HARNESS $300. HOW MUCH IS YOUR TIME WORTH? IF YOU JUST USE YOUR OLD PANEL YOU CAN JUST WIRE IT YOURSELF, NO BIG, JUST TIME CONSUMING AND DO LIKE DRAG LINK SAYS AND KEEP THAT "NEW" WIRING DIAGRAM SOMEWHERE SAFE CAUSE YOU'LL NO DOUBT USE DIFFERENT COLORED WIRES FOR SOME THINGS. IF YOU USE CRIMP CONNECTORS TRY LIKE HELL TO FIND A RATCHETING TYPE CRIMPER THAT WILL MAKE THEM NEVER COME APART. IDEAL MAKES ONE FOR LIKE $40 AT AN ELECTRICAL SUPPLY STORE. MIGHT HAVE TO ORDER IT. SHRINK WRAPPING OVER BUTT SPLICES LOOKS SLICK TOO BUT TAPE WORKS, YOU CAN ORDER PLASTIC WIRE LOOM IN ANY COLOR FROM SUMMIT FOR CHEAP, AND THE SPECIAL FASTENERS FOR SAME AT PARTS HOUSES-BLACK ONLY
