This is an original Ford Mustang 1964 1/2  Underdash / In Dash Main Wiring Harness.  There is one section of wires cut,  marked with yellow tape.  I do not see any damage, but there may be a bad wire or cut somewhere in it.

It is part of a group of harnesses that I am selling that were pulled in the early 1980's and stored indoor. 

Original Ford

 The wires are soft and pliable, not some harness hacked up and sitting in a junk car with no windshield for 20 years.  

Dallas area, no snow or salt issues.

I do combine shipping.
