wiring problems

[stockgp]

i've got a 90 gp, and i'm trying to take the digital dash from an 89 and put it in mine. so far, i've been unable to find a wiring diagram to make it work. any help would be appreciated

isn't this the same as what is here?

The GP dash is different than that but it may use the same basic setup on connectors.

I thought I remember someone saying once that the Grand Prix digital dash is made by Delco, therefore it has the same pinouts as the 90 analog cluster. In fact, I know others have gone the other way from digital to analog.

well, see, the dashes are both made by delco. but, the pinups are different. in fact, my harness has almost half as many wires as the 89 i took the dash from. the link to the other page might be very helpful, but i would still like to use this dash, which is completely different from the supreme's. my problems with the dash are 1-the oil pressure gauge doesn't work; 2- the led for the speedometer only lights up with the parking lights; 3- the odometer also does not work. now, maybe you all can see why i need the wiring schematic.

Was your original cluster a gauges cluster with oil pressure, volts, etc? Or was it a base cluster?

[stockgp]

my original cluster is the analog cluster with voltage, oil pressure, etc. i just don't want to start plugging wires to make the other dash work and end up frying it.

I used to have a Grand Prix SE and i put a dash from a 93 Grand Prix GTP and it worked without any changes just plugged in and worked. :idea:
