ABS without stock cluster?
Will the ABS work without the stock cluster in place?
Looks like I'm going to a digital dash because my cluster is dead. I read that the speed readout from the speedometer board to used by the ABS system
Is that true?
If so, will ABS function at all without it?
Thanks

You'll have to dig into the shop manual, I'm not sure if the cluster outputs to the ABS system. It may just tap in to the speed sensor's output.
That said, you may just want to get a good used JDM cluster, read my write-ups on doing it. Many times that's much cheaper and easier (and will give a better result) than going to a digital dash.

I don't have confidence that the replacement cluster wouldn't die as well
I'm happier spending 2-3x the money and getting something brand new, provided there are no huge hurtles to making it work with the rest of the car
I appreciate your input though

You can get a used JDM cluster for $200-400, and in general the later clusters (94 and up) are much better built and more reliable.
Also, if you read my writeup, you can swap your odometer chip into the new cluster so you have the original mileage

Looks like the 2 systems don't really interact
The only connection I can see is for the warning light on the dash
That's good
Now I just need to work out the best way to get a speed signal to the ECU without a stock cluster
The 2 wire sensor from the transmission appears to go straight to the cluster and doesn't appear to be used by anything else. Probably have to clip that and convert the signal to digital to feed it into an Adaptronic modular ECU

And I understand a desire not to negatively affect the value of the car with a higher km dash, but I doubt adding an aftermarket digital dash...and possibly sacrificing ABS is going to do anything positive for it's value either.

I misspoke, the entire cluster isn't dead. The odometer died last year, I replaced the caps, it came back for a few weeks and went out again.
6 months ago, my speedo and tach were dropping signal occasionally. I added a better 12V and a better ground to the cluster and both were reliable again.
Until last weekend when both became intermittent and then died a couple days later.
Warning lights, fuel gauge, temp gauge, etc all work normally.
Before I dump a bunch of money into it, I'll pull the cluster again and look for obvious issues with the speedo/tach board, but odds are high that I make the change.
I imported the car 7-8 years ago and it has generally worked very well. I doubt I'll ever sell it - it just becomes a bit faster and a bit less stock every winter
Regarding the accuracy of the odometer, it would bug the **** out of me to look at 100k on my dash every time I drive it, so I'll want to address that either way. Maybe that's weird.
