Instrument clusters

[old Rusty C10]

I need a bit of schooling about instrument clusters

I know there are differences between 73-80 and 81-87
Is there differences between the wiring set up for guage and idiot light?
What differences do i need to overcome?
Im thinking of replacing my guage set up with another the thing is i dont know if mine had idiot lights or guages as the PO put in some not working aftermarket temp and oil guages
I would prefer the stock guages in the dash.. neither cluster has a tach

Also there is no difference between the cluster that came from a stick as opposed to an automatic other than the black tape that covers the gear selector section?
TIA

Don't know if this will help. Its mostly about Tach's. http://www.73-87.com/7387garage/inte...achometers.htm But good info.

There are differences in the wiring between gauges and no gage clusters. There is no difference in the cluster between manual and automatic. I will try to illistrate the differences in wiring. The number is the color of the wire and this is how it would look if the cluster was face down on a table.


No gages

150 14
33 15
25 39
939 empty
39 empty
35 150
31 237
8 empty
11 30

with gages

35 150
150 14
30 15
39 237
31 empty
39 931
150 39
8 33
11 30

The repeated numbers are correct and this will work from 78-82. My source is the GM Wiring diagram.
