*Urgent*Instrument cluster wiring question

David Neibert

SCCoA Admin
On my 93 SC, I need to know which wires (wire # and color) coming off the instrument cluster are for the following gauges.

Tach
Oil pressure
Coolant temp

Thanks, David
 
Oil pressure indicator to oil pressure sending unit - #31 - W/R (white w/red stripe)

Temp gauge to temp sending unit - #39 - R/W (red w/white stripe)


Here are the ones that I think may involve the tach:

Elect. sw. to ignition coil neg. terminal - #11 - T/Y (tan w/yellow stripe)
Sender signal to amplifier - #150 - DG/W (dark green w/white stripe)
Sender signal return - #359 - GY/R (gray w/red stripe)

The tach signal wire should be Tan/Yellow, at least the one from the 93 cluster I put in my base bird was.
 
The Tac is T/Y in my reference (Tan/yellow stripe) up to connector C228, where it goes White/pink, into the VMM, then back out as T/Y. to the gauge.

Wire Color Code Identification

BK : Black
BL : Blue
BR : Brown
DB : Dark Blue
DG : Dark Green
GY : Gray
GN : Green
LB : Light Blue
LG : Light Green
PK : Pink
O : Orange
P : Purple
R : Red
T : Tan
V : Violet
W : White
Y : Yellow

Where two colors are shown for a wire, first is basic color and second is stripe marking (tracer).
For example, BR/O is brown with orange stripe.
