stockgp Posted September 12, 2002 Report Share Posted September 12, 2002 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 Quote Link to comment Share on other sites More sharing options...
musthavemuzk Posted September 12, 2002 Report Share Posted September 12, 2002 isn't this the same as what is here? http://www.w-body.com/upgrades/88-91cutlass-cluster/index.html not sure this is why i ask and not just say do this.

Guest Anonymous Posted September 12, 2002 Report Share Posted September 12, 2002 The GP dash is different than that but it may use the same basic setup on connectors. Quote Link to comment Share on other sites More sharing options...
GnatGoSplat Posted September 12, 2002 Report Share Posted September 12, 2002 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. Quote Link to comment Share on other sites More sharing options...
stockgp Posted September 14, 2002 Author Report Share Posted September 14, 2002 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.

GnatGoSplat Posted September 14, 2002 Report Share Posted September 14, 2002 Was your original cluster a gauges cluster with oil pressure, volts, etc? Or was it a base cluster? Quote Link to comment Share on other sites More sharing options...
stockgp Posted September 15, 2002 Author Report Share Posted September 15, 2002 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.

NORBI Posted September 19, 2002 Report Share Posted September 19, 2002 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. Quote Link to comment Share on other sites More sharing options...
