For anyone wanting to install aftermarket gauges in your 85 mustangs; here is the wire break down for the 85 gauge cluster. The how to is up on my site but I have not added in the wire colors to that page yet. That should be updated monday. For the how to go to
www.flemworld.com look under How To's>>85 How To's..Upgrading the gauges..
1. Dash illumination = Light Blue with red stripe
2. Ground = Ground to Chassis but the wire color is black.
3. Fuel Guage = Yellow and black hash line
4. Oil = White with red stripe
5. Water = Red with White stripe
6. Tach = Dark green with yellow stripe
7. Safety belt light = Dark green with light green stripe
8. High Beam = Light green with black stripe
9. Left turn siganl = Light green with white stripe
10. right turn signal = White with light blue stripe
11. Low oil light = Red with yellow hash + Black with light blue stripe Red is hot, Black is the trigger from the relay.
12. Upshift light = Black with yellow stripe + gray with black stripe. Black and yellow is hot, gray is trigger from relay.
13. Brake light = red with yellow hash + Pink with white stripe. red is hot and pink is trigger from relay.
14. Power (Ignition "key" Wire) = Red with Yellow Hash line Note: Should be two of them. Run all the gauges off one of the hot wires and if you are using any of the list above hook them to the otherred wire. Else split the gauges between them.
