How
To Convert From An
Idiot Light Instrument Cluster
To A Gauge Instrument Cluster
Contributors: Xtremeclonedss, 80 Mich Bu and Malibuplotter
If you would like to
change out your plain speedo and cluster to a cluster with a round
speedo and tach, there is no need to remove your wire harness, this is a painless
procedure! No need to pass any additional wires through to the engine
compartment! See below for simple instructions:
| 1. |
Remove
cluster bezel and don't forget the 4 screws on the bottom and 2
on the sides |
| 2. |
Remove
cluster lens and "PRNDL" indicator. Carefully
remove the push-on "PRNDL" cable from the column
shroud. |
| 3. |
Remove
the cluster. The cluster connector will stay with the dash
pad |
| 4. |
Using
a very small screw driver, release each wire one
at a time from the long speedo plug and place it in the correct
numbered position on the plug for the round guages. Going
from the long speedo to the round speedo you will have two wires
left over. I just taped them so to not cause any grounding
problems and left them alone out of the plug. |
| 5. |
Now
put them back according to the diagram (below) marked
"Round Speedo With Gauges". |
| 6. |
OK,
you're done inside the car. Re-install the gauge cluster
onto your dash pad. |
| 7. |
Remove
the brown wire from your alternator. If you have a cluster
WITHOUT a tach, just coil it up and tape somewhere under the
hood - DO NOT CUT IT OFF! |
| 8. |
If
you DO have a cluster with a tach, I recommend tach filter (GM#
14062505) from any GM dealership or off any Cutlass, Monte
Carlo, Regal, El Camino or Bonneville (1978-1988) at a junk
yard. |
| 9. |
Change
your water temp and oil pressure sending units (for
gauges). You can get them off the above mentioned cars in
a junkyard or a GM dealer. |
| 10. |
Amp
gauge is already OK |

You're
done!! |
