Something like this would help. I would splice them in where ever you can. https://www.amazon.c...p/dp/B00152RH4O

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.

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

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.

Good deal, thanks a million!  I'm on vacation next week so it's priority on my to do list.

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.....

 

 

 

1989 DIS:

 

Plug C1:

Pin Wire color Title

 

A) Orange Battery constant Power

B) Pink/Black Ignition switched power

C) Yellow Dimming/lighting

D) Gray Dimming/Lighting

E) Black/White Ground

F) EMPTY

G) Light Blue English/Metric Switch

H) Black Ground

 

Plug C2:

Pin Wire color Title

A) Orange Serial Data Uart

B) Green Vehicle Speed

C) Violet Fuel Level

D) Black Ground

 

 

 

1991Instrument cluster:

 

* This should be a plug with 2 rows of 16 pins, one side is “C”, the other is “D” Since only a few pins are used for the DIS I am only showing the ones that you need for the install….

 

Plug side C:

Pin Wire color Title

10) Yellow Dimming/Lighting

11) Gray Dimming/Lighting

13) Orange Serial Data Uart

14) Black Ground

16) Pink/Black Ignition switched power

 

Plug side D:

Pin Wire color Title 1) Black Ground

9) Light Blue English/Metric Switch

13) Violet Fuel Level

15) Green Vehicle Speed

16) Orange Battery Constant Power

Interesting the B's turned into a smiley, at least it formatted correctly and not into a big block.

Thanks for doing all of this, really lost but this should help immensely.  It won't be until next week when I start on it again as I work all weekend.  I will update my progress and see how it turns out.  I might ask a lot of questions and post pics as I go too. 

 

Do you know why my 91 wasn't prewired?  Isn't that very odd?  The pictures of the radio mess might explain why.  Maybe it was messed with when the aftermarket stereo was put in.  I wouldn't think that the stereo mess with interfere with the rest of the car's harness but just wondering.

I have never come across a 91 that was not pre wired. Just put all three grounds together it will be fine.

Which is odd since only like 200 1991s actually got a DIC.

Even the most base 1991s had the wiring for DIC. Even sedans have it. Not sure about convertibles, I have never seen one at a yard to look.

I seem to remember reading some time ago about having to dig around to find the plug. granted I really don't follow the Cutlass very thoroughly but for some reason I thought I read that in a thread a while back

I assume if it's prewired it will be like the 89 car tied into the main harness.  I will look around some more when I have time.  I also found some connectors that are heat shrinkers and have material in them to seal the wire internally protecting it from oxidation and the elements.  I might try those.

 

On cars that were prewired, where should I look?  Behind the ECC or what?
