DIC for my International.

[94 olds vert]

I am not seeing the DIS connector. I have never come across a 1991 that was not prewired before. I have opened up a good amount of 1991s to look for wiring. Instaling a DIS is not that hard.

 

INSTRUCTIONS:

 

Oldsmobile Driver Information System:

 

*not responsible for errors during installation such as damaged DICs, car fires, house fires, total city fire, end of universe due to division by zero through the following of the info provided*

 

 

The Driver Information System is used on several Oldsmobile model lines. This includes A, G, H, L, N, and W-bodies of the 88-91 era.

All units are physically identical, but have some internal programming differences.

 

Wiring colors can vary greatly, so verify all wires by placement. This unit has a pigtail on the rear, and colors on the pigtail differ from colors within the vehicle wiring harness.

* all vehicles examined omit connection to this wire, even though it is present on the unit pigtail

$ not necessary to be hooked up. most vehicles examined omit this wire.

% only hooked up on vehicles if equipped with an E/M input

 

 

and what they do:

DIS-C1-A Constant hot source, it is power for the DIS memory. Digital clusters would have this wire, but if your car does not have a digital cluster, the radio will have a constant hot wire for it's memory that would be a good power source.

DIS-C1-B Switched ignition feed, hot in run. it powers up the unit when you start the car. You can tie this to the cluster or radio. both have a hot in run wire.

DIS-C1-C Vacuum fluorescent dimming input. It controls the digital display intensity. you can tie this to a VF wire.

DIS-C1-D Button Illumination (adjustable backlighting)". You can hook these to the backlighting for the cluster or radio.

DIS-C1-E Ground.

DIS-C1-F Not used and not defined

DIS-C1-G English/Metric input, externally set by cluster or switch to set DIC unit mode, if wired.

DIS-C1-H Ground.

 

DIS-C2-A SERIAL DATA INPUT, which the DIC gets info from the ecm/pcm for calculations and display.

DIS-C2-B VSS signal input. this can be hooked to the cluster feed for the speedometer.

DIS-C2-C Fuel level gage input. this can be hooked to the cluster feed for the fuel gauge.

DIS-C2-D Ground, connected only if E/M input is present(without regard to mode)

Oh wow, that's intimidating.  I'm going to open up the dash on the 89 car and look around.  I have the pigtails on the 89 car just need to figure out where to connect into the 91 car.

[94 olds vert]

It is honestly not that hard.

[jiggity76]

I'm not sure what to do with the information given to me.  Am I suppose to match up colors of wires together?  I've never done electrical work in a home or car.  I printed off the thread posted by rockfangd but again, don't know what to do with the info.  I just got to play around with it tomorrow and maybe I'll figure it out.

[94 olds vert]

Take as much wiring out of the 1989 for the DIS to transfer into the 91.

Alright.  Thank you.  I'm probably making it harder than everyone says it is but I'm learning.  Thanks for everyone's  patience.

[Imp558]

how soon are you doing this install?

[jiggity76]

how soon are you doing this install?

I got the 91's dash tore apart right now.  I'm going to work on the 89 car tomorrow.  I don't have a timeframe, just starting the project and doing a little at a time.  I work a unusual schedule - 12 hour shifts so whenever I have time.  Also trying to get my 87 GMC 4x4 project done first right now.

[Imp558]

give me a couple days I'm crazy busy right now. I will chart it up for you. you can't just start matching up wire colors because they use the same wire color for multiple things, for instance the wire that goes to a fuel pump relay from a computer looks exactly like the one that goes up for the vehicle speed signal to the instrument cluster.

I greatly appreciate that, thank you so much.  I can work on other things in the meantime, absolutely no rush.  I don't want to mess anything up on such a rare option piece.

[jiggity76]

Worked on the 89 wiring harness.  Got the upper dash out and it seems I have to pull the lower dash out too?  The wiring harness is taped to the vent tube and a electrical conduit system.  If I do have to pull the lower dash, anyone know where all the bolt locations are?

 

 

Lower section of wires is the cigarette bulb, HUD backlighting, and most importantly the DIS pigtails.  Big one on the left is the digital dash pigtail.  The ones on top is the stereo.

 

 

There's one last wire location before this end is free, the power trunk release button on the lower panel under the steering wheel.

 

 

This is behind the glove box, really worried about having to mess with this.  Please tell me I don't.  The wiring harness is to the left of the glove box and is taped to the air ducts and a wiring conduit - that is where it's holding me up.

[94 olds vert]

For the DIS, you only need to connect a few wires to get it to work. A power wire from the cigarette lighter that will power the DIS. A ground to ground the DIS. Then tap into the fuel, and tach. maybe speed VSS?

 

If you search for the digi ub3 swap you find the color of those wires.

Imp558 is going to help me out thankfully.  How do you identify which wire goes to what component?  I'm going to stop until I hear back on the diagram.

Thank you!  This will help a lot.  Should I follow the wires from the pigtails back or just cut them and splice them in where I can.

[94 olds vert]

Something like this would help. I would splice them in where ever you can.

Thanks again.

[Imp558]

Those things are bad news in the long run. Solder is the best method but honestly its better to twist and tape than use something that severs strands and then leaves the copper exposed to oxygen.

[jiggity76]

What about the compression ones?

[Imp558]

If it doesn't seal it allows the wire to oxidize.

[jiggity76]

Would the twist kind like on the radio and then tape work, sealing it and preventing oxidation?

 

Did you find a replacement regal?  I can't remember if you wanted a coupe or four door again.  There's a nice 91 Buick Regal GS coupe on CL if that's what your looking for.

I'm writing the pinouts up tonight.

Okay, you should be able to cut and paste the following into a text editor and print it.

 

First, every pin on every plug has a designation, for instance on the 89 DIC the plugs are formally known as "C1" and "C2". The pins on those plugs are lettered so you should see little letters embossed in it that correspond to the chart below.

The plug on the Instrument cluster should have numbers embossed in it or at least 1 number at the beginning and end of each row.

 

Second, I don't have a picture in Alldata for any of these plugs but I suspect the Instrument cluster is a 2 row plug with 16 pins per row, each row is a letter "C" or "D". If there are no letters or numbers just count through the pins and figure them out with the chart. There should be an "A"/"B" plug too.

 

Third, You don't need to CUT any of the wires to the Instrument cluster, all you need to do is bare a little spot and wrap the wire from the DIS around it and tape it up well - done. Naturally solder would be better but that will work fine.

 

Fourth, There are 3 grounds on the DIS, if it were me I would twist them together and solder or crimp a ring terminal on them and stick them on a bolt. I reflected the grounds on the Instrument Cluster if you want to tie into them.

 

 

If something doesn't line up with this chart take pics of the plugs and post them and I'll figure it out, some times things change mid model year and we have to extrapolate from a different year.....
