Ouch, shows what 60yp wiring and enough knowledge to be dangerous equals. Id spring for a whole new wiring kit (if youre not looking for stock) from Painless or AAW.

That is just terrible, that car should never be driven in that condition.  This
shows that the electrical systems of that day were never designed to last
many decades. 

I would HIGH PRIORITY investigate getting a replacement wiring set, and
plan to replace EVERYTHING.  If a good set isn't available, plan how to
have a custom replacement built up, possibly based on the original after
removal.  Worst case you would be much better off with one of those
UNIVERSAL car wiring sets, adding whatever is needed to fill out the Cad
functions. 

Part of the problem is those ancient poor quality connectors oxidize over
time, the resistance increases, they start running hot, and the whole
process snowballs to the point of melting things and possible short/fire. 
Don't hang onto that ancient technology, get improved replacement
equipment for this critical function.  Better fuse block, better connectors,
use properly sized FUSEABLE LINKS in the major power feeds.  Keep
that car on the road, upgraded as needed. 

The harnesses I build tend to be easier to service than originals. Bruce Roe

If you are into DIY, I find DEL CITY in Milwaukee can supply quality low
voltage wiring, waterproof connectors, tools, etc in a variety far beyond
any local store.  Prices reasonable, they aren't specializing in cars at all. 
Great on line search.

took the harness out last night
will replace the damaged wire, for now, I haven't fired the car since I have, so I would like to know if it starts and trans work before I really go deep

You don't need the wiring harness of the car to do that.

Disconnect the main power wire that goes from the starter to the fuse box to take the car's wiring out of the equation.

Run a power wire from the battery + terminal to the coil (preferrably with a switch in there somewhere).

Run a wire from the starter solenoid to the battery with a pushbutton switch.

Turn on the power from the battery to the coil.  Press the switch button on the other wire to engage the starter and at least you can let the car run that way, if you're concerned with getting in too far without knowing the condition of the engine and transmission.

thank you, Dan Leblanc,
I will try this
part of it is I got the car with all the wire disconnected under the dash and engine bay I am trying to figure out where all the wire goes its a lot easier for me after I know where everything goes to work on it

If you try to start it, don't leave a wire connected between the battery and
the coil + for very long, or you may burn up more stuff.  A ballast resistor
needs to be in that path to limit current, which only is shorted when
actually cranking the engine.  Bruce Roe

For a temporary run I would use a wire to the coil with alligator clips on the ends. This way if something starts to go bad in a hurry you can just yank the wire and the car will die immediately.
