90-91 vs 92-96 Instrument Clusters

[Ccmano]

Learned something new today. 90-91 instrument clusters are NOT interchangeable with 92-96 clusters. At least not the LCD module. Everything else worked fine.

The tach on my 90 cluster is way off, some of the lights are out and the oil pressure gauge is off. So I found a great deal on a newly rebuilt low mile 96 LT4 cluster. Did the swap today only to find out that the LCD display went wonky showing jibberish. My frist thought was the new cluster LCD was defective. I had always thought all years were interchangeable.

So I sent Brian Thompson at Batee.com an email with a photo of the new cluster jibberish. Much to my surprise and satisfaction I got immediate reply (that’s customer service). He informs me that the LCD’s are indeed NOT compatible. The “electrical protocol “ was changed between the two.

The good news is that I can swap the LCD modules (the old LCD is still excellent, although I may rebuild it anyway) and I’m good to go. The LDC modules are a simple plug in.

That's been I'd say 'common knowledge' for years!!! I'm surprised you actually didn't ask first or that you weren't aware.

Yes Bryan has excellent service!!!!!

I'd think it way more appropriate for someone to use a cluster that's actually correct!!!

Are we having a bad morning? Did my post insult you somehow?

Common knowledge is a curious thing, it’s only common to those who actually know. I searched the forum here and over at Corvette forum, both the ZR-1 and regular tech forums and found nothing. Did find several posts claiming they were interchangeable. If you want to be helpful why don’t you find one where this is documented.

What I do with my car is my business not yours. On my 180k mile Z it hardly matters whether the cluster is “correct” or not. I happen to like the later one better.

The purpose of this post was to help others that might be looking at the same thing and to document what you consider “common knowledge”.

If you can’t say anything positive you might want to keep it to yourself.

My 'MORNING' is GREAT and I also have a 'RED CAP'!!! YOU?

Just one of many threads regarding 'clusters'

http://www.zr1.net/forum/showthread....hlight=cluster

I've actually documented by PART# year/model of likely compatibility on for sure the CF and quite likely here also!! If you ain't concerned with 'warning light" orientation etc

In 2013 on the CF I mentioned these thoughts and that was from research and references from maybe '07 or so.

https://www.corvetteforum.com/forums...post1583417163

And I corrected 'Brian' to Bryan

Cluster information I'm sure should be more easily documented!

You are correct though - what you do with your car is YOUR business

*** I mentioned only being maybe more appropriate 'My thought'only!!!

I'm over this - ARE YOU?

[Ccmano]

I suspect we could go back and forth on this many times. We have both said our piece. I will leave it at that.

I tell you what... why don’t you provide me with all the cluster information you have, I will add it to what I have found and I will write an article for the Heart of the Beast Registry publication. I will also post it here and over on CF.

In that way we help the most owners of Z’s and C4’s in general.

What do you think?

I am surprised your search came up empty. I know I have helped on CF with several wanted to swap the 90-91 to a 92-96.

Yes the LCD as you found is different. but you will also find that there are some Perimeter warning lights that are not correct..

Looking at your picture, what year cluster did you get? I am thinking the lower right warning light is not correct. I found when I had a 1996 cluster with my 91 dash I need to swap 2-3 Warning lights. I actually just came across that cluster recently with my wiring changes.

Speaking of Clusters, anybody know where I can get a new Cluster overlay made?

I included this thread in -Solutions- (third post - ZR1 Electronics under KEYLESS ENTRY, TACHOMETER, CRUISE). The technical information is greatly appreciated. I did not know such differences in clusters existed but having said that it seems Paul has a handle on the most obvious issue that comes up once in a great while (Tachometer calibration).

the white does look a bit more defined than the yellow/orange..

Hmm.. I might need to consider doing some changes again in the interior

Jeff,
When you put the two side by side you can clearly see difference. See the attached photo.

Cliff,
Excellent! Your “Solutions “ threads are invaluable.
