This is the alternator wiring harness (includes all wiring from your alternator to your battery negative terminal).   Fits 1987 Daytona Shelby Z with Turbo II engine.  
 
Minty fresh, NOS Mopar.  If you are looking to restore an 87 Daytona Shelby Z, this is what you want.
 
  Take a look at the harness in your car...and specifically the current condition of your negative battery terminal....  Is it all beat up? 
 
  Also, if you have been having issues with hall effect pickup loose/bad connections, your harness may be shot.  A loose or bad connection at your distributor wiring will cause the car to die intermittently which can leave you stranded.  Not fun.
