The problem seems to be as Dennis said 

I have opened up the rubber tubbing the 5 wires are in  The tubbing aprox 10 inches is rather damaged crincked hard etc 

So think will  cur and remove aprox 24 inches of the 5 wires  and place them back in a new tube 

The most likely splice connection will be the standard crimp type  …..  is there any reason toe soldier the connection instead ?

Use shrink tube on the 10 splices /.connections 

and place them in this tubbing from West Marine   

And finally secure the tubing with the wires to the rear sheet metal rather than having them sitting on the sheet metal over the muffler

Any thoughts, comments or suggestions 

Living in Santa Barbara West Marine seems to be the best choice for locating the tubbing and quality wire
