Hope you will except a question from a 49 F3 pickup that is being converted to a 91 5.0. --have complete wiring harness and engine from rad to end of drive shaft--need to know if a 94 instrument cluster would be plug compatible to this wiring harness-not worried about the dash fit as it will be custom--One other thing when its done this old 49 f3/mustang will actually haul the 4 hoofed name sake of your 4 wheel mustangs.
 
The dash harnesses should be different animals. They have different idiot lights and the SN95 has an electric speedo signal. You would need the SN instrument harness and a way to accomodate the VSS signal wiring (make your own coming from the trans to the cluster), and then do some splicing and melding of this harness into your fox III's body harness.
 
Let me see if i can help. I have done MASSIVE research on this topic as i am inprocess of an SN95 dash swap in my 93.


The dash wires are the same color from 1991-1998. The connectors are different, and the wires are on different sides, but just swap connectors, and everything will work save for the speedo.

To make the Speedo work you will need the VSS from a cruise control mustang from 1987-1998. you will need to run the 2 wires from the VSS to the dash. on the back of the SN95 cluster you will see the lable for the speedo. there are 4 connection points (Batt, Ground, Speed In, Run).

take one leg of the VSS (not sure which one, never could find exactly what to do) to the Speed in, the other leg goes to ground. then you will have a working speedo.

If you have anymore Q's i would be glad to help!
