here is the cleanest underdash wiring harness I've ever seen for 71  Mustangs.  No Tach.  Removed from a 1971 coupe,  there are no cuts, frays or splices.  Colors are bright.  No rust whatsoever in the fuse box.  Not proper for 72-73 because of the seat belt warning light. I am parting out a low mileage 1971 Coupe with a standard ginger interior and will be listing all the parts within the next few days.  Add me to your list and check my listings. I combine shipping on all my parts.  If there is anything else you are in search of for your Mustang project, message me.  I just may have what you need. I guarantee all my sales.  If there is anything you are not satisfied with, let me know.  I will take care of it.  Please leave me positive feedback if you are happy with your purchase.  If not, contact me and I will rectify it.  Bob  631-833-0305 Additional keywords;  Mach 1, fastback, convertible, coupe, GT, Shelby 350 500, Grande
