instrument cluster swap

[Clyde]

Does anyone know whether or not I can swap the basic 92 lumina cluster with the fancier tach and gauge cluster of the same year?

I have a 3.1 reg lumina and I bought a Euro cluster and ecm out of a 3.1, swapped them out and and it did not work ??

I just swapped a 94 cluster with tach into my 93 that had the base cluster. It is not plug and play. You need to switch a bunch of pins in the connector to the cluster and you need to run a wire from the coil pack for the tach signal.

I found this when I did a search:

For the Base Cluster
C3 - Pink/Black - Ignition Power
C4 - Yellow/Black - Low Coolant Light
C5 - Tan/White - Brake Light (parking brake or low brake fluid)
C6 - Brown -Charge Indicator
C7 - Dark Green - Coolant Temp Indicator
C9 - Black - Ground
C10 - Brn/Wht - SES Light
C11 - Tan/Blk - Shift Light
C12 - Lt Grn/Blk - Antilock light (if so equipped)
C13 - PPL - Fuel Level indicator
C16 - Lt Blue - Left Turn signal

D1 - tan - Oil Pressure Indicator
D2 - Yellow - Fasten Seat Belts Indicator
D8 - Gray - Dimmer switch
D12 - Black - Ground
D13 - Dk Grn - Speedometer
D15 - Dk Blue - Right turn signal
D16 - Lt Grn - High Beams

Ok, here is the pin out for the gauges cluster.

C2 - Black - Ground
C3 - Gray - Dimmer
C5 - PPL - Fuel Level
C7 - Dk Grn - Coolant Temp
C9 - Lt Blue - Left Turn Signal
C11 - Yellow - Fasten Seat Belts Ind
C13 - Tan - Oil Pressure Indicator (Did not work for me, I think I used D8 or D10. Follow the trace on the board)
C15 - Brn - Charge Indicator
C16 - Yel/Blk - Low Coolant

D1 - Dk Blue - RH Turn Signal
D2 - Lt Grn - High Beams
D3 - Tan/Blk - Shift Indicator
D4 - Pnk/Blk - Ignition Power
D5 - Dk Grn - Speedometer
D6 - Black - Ground
D9 - White - Tach Wire
D11 - Pink/Blk - Ignition Power
D13 - Tan/Wht - Brake indicator
D15 - Lt Grn/Blk - Antilock indicator
D16 - Brn/Wht - SES Light.

for the two power wires, run a jumper from one to the other. Which is what I did. As for the tach wire, you will need to get under the hood and unplug the left connector on the ICM. There are 5 wires in that connector. They are:

Tan/Blk - Bypass Wire for ECM
White - Tach signal for ECM
White - Tach signal for Instrument Cluster (This is the one you want)
PPL/Wht - Reference signal for ECM
Black/Rd - Ground from ICM to ECM.

Watch the green wires when you are re-wiring the plug, they are the same color green but do different things. It took me all day, but my new cluster works fine. If your tach is stuck at 8000, take the front plastic off and move the tach to zero carefully and you should be all set.

While I was at it, I replaced all the burned out lights in the heater/AC control. 6 little bulbs.

You will need to replace the temp sender with one that is made for the gauge cluster or it will read cold all the time.

Hope this helps.
