95WhitePrix Posted February 10, 2021 Report Share Posted February 10, 2021 Do all 1995 Pontiac Grand Prixs come prewired for the Heads up display and Driver's information center? I couldn't find the wires on mine. Quote Link to comment Share on other sites More sharing options...
94 olds vert Posted February 10, 2021 Report Share Posted February 10, 2021 Did you look behind the gauges? There should be HUD, HUD switch for adjustments and DIC that group of wires is usually tucked up somewhere behind the dash. There will not be a temp sensor wire, as that is separate. 95WhitePrix 1 Quote Link to comment Share on other sites More sharing options...

So every 1995 model definitely had these wires somewhere in them? Quote Link to comment Share on other sites More sharing options...

Based on what I have read here and my personal experiences with these cars. I'm thinking they should be. You can check behind the radio and climate control. There is a chance they are back there.

I saw some square white plug behind the climate control, but I don't think that the HUD thing is white, is it? Quote Link to comment Share on other sites More sharing options...

I watched a video on YouTube of someone installing one in a 96 and the plug for the DIC looked similar, but it was black. Quote Link to comment Share on other sites More sharing options...

Does that plug have enough wire to reach where the HUD and DIC should go? There should be three plugs back there. Sometimes they can be taped up to another section of the harness. In my 1994 Cutlass Supreme, I had to cut the tape that was holding the wires onto the harness. I think that car had a blue plug for the HUD.

I don't think it is, but usually they are all bundled together, and I didn't see any other plugs around it. Quote Link to comment Share on other sites More sharing options...
94 olds vert Posted February 11, 2021 Report Share Posted February 11, 2021 I haven't heard of any 94 to 96 grand prixs not being hard wired. That's a first for me. Quote Link to comment Share on other sites More sharing options...

94 olds vert Posted February 11, 2021 Report Share Posted February 11, 2021 Unless someone else knows where to look. Typically, behind the gauges or radio/climate control is where I thought they would generally be. 95WhitePrix 1 Quote Link to comment Share on other sites More sharing options...
