CCD Bus Free Digital Dash
The 1990 & newer EEK's (all preOBID2) use a "CCD bus" in communicating between computers and other digital devices. Its a cool, high tech idea that can become quite the headache when doing modifications.
As far as installing a digital cluster, you can use a CCD bus
dependant cluster (such as a 1992 Imperial digital cluster in a 1992
Dynasty) however I have found that CCD bus clusters tend to:
-Not always work
-Not work as long as the CCD-free digital clusters
-Are harder to troubleshoot if something goes wrong
My first digital dash install on my Dynasty was a 1992 Imperial cluster which lasted for about two years when the cluster died on me.
At that point I wanted to look for a CCD bus free cluster.
My search found two immediate options: The 1988 New Yorker (FWD) digital cluster, and the digital cluster used in AA body LeBaron's (AA only, not to be confused with the LeBaron GTC, GTS etc).
So I watched the local yards and eBay and eventually got my hands on a 1988 New Yorker cluster, which is the "bar type" display. The one I found had been rebuilt by Motorola (who made alot of the EEK digital toys btw) and came out of a car with only 79,000 miles on it- which ended up being a much brighter display than what is typical on digital clusters.
I eventually found an other 1988 New Yorker cluster in the yards locally- that one from a car with only 45,000 miles on it- and sure enough, that one had a darker display.
Eventually I found a 1993-1995 AA body LeBaron with a digital cluster in the yards, this was the "fake sweep" digital display like the one used in the 1992-1993 Imperials. I advise AGAINST any cluster that uses that kind of display because it is a LCD display and due to either cheap parts or bad design, the display will slowly black out. The one I found had 190,000 miles on it and the right speedo digit was almost completely blacked out (due to the LCD actually decomposing).
The AA body Lebaron cluster does mount differently to the dash, it will not fit into a AC/AY body unless you swap cluster housings. If you can find a housing for a digital AC/AY cluster, you can throw hte AA cluster's electronics in it, and it will bolt up and fit flawlessly. Since my first digital cluster (that 1992 Imperial one) had burnt out I had a spare housing laying around.
The AA body digital cluster, especially the later "fake sweep display" one is probably one of the most rare digital clusters, you are probably best apt to find a bar style display such as a 1988 New Yorker cluster.
Enough of the talk- now for the pics:

Here is the 1993+ AA LeBaron cluster installed, note the blacked out
part of the speedo digit.
Now that you've seen the pictures- you're prolly thinking "how hard is this?"
Its actually fairly easy if you know the pinouts for the clusters in question.
Thankfully the CCD-free clusters use the same wires your analog cluster uses, so all you have to do is cut out the old analog cluster connectors and wire in the new ones and it will plug in and work. Here are the pinouts:
