1973 Mustang Underdash Wiring Harness - Standard - Original.  This Engine Compartment Wiring Harness is in good  shape with most of the connectors still intact.  Each of the connectors are in nice shape but there are some areas (marked with blue tape in pictures) that the wiring will need to be repaired.   The wiring still has it's original color coding on it and looks good.  This is for a standard dash without a Tach or 3 guage pod.  This wiring is for a 73 Mustang and is different than 71 (71 does not have seatbelt buzzer connectors next to the drivers and passenger seats).  If you are looking for a good Underdash Harness for your restoration, then this is for you!!!
