(searched) JDM gauge cluster wiring questions

[420sxse]

I'm dead sure this has all been covered before but I can't find much. I replaced my '92 no ABS/HICAS s13se coupe's digital cluster with a JDM one. I plug'n'played it into my harness. I have the JDM speedo sensor, but it isn't installed yet. The tach, from what I can feel, seems accurate. I have no clue about the speedo (this is the first time the car has given me any velocity indications in three years ) from what I have gathered, the km/h readings are not accurate with the USDM speed sensor? I may not give a flip anyways; I am so used to reading speed from the tach. My main issue is that the dimmer doesn't work (don't like it so bright); the cat overheating light (wire in a resistor, remove the light bulb, or ignore it, I read); and the low windshield washer fluid light on the bezel won't go off. Any helpful comments, tips would be greatly appreciated. thanks.

Bump. I still can't find any info on these wiring issues. I'm going to be taking the dash apart again for painting, and would like my dimmer back (and the other lights to work. I figure I'll just have to remove the catalytic converter warning lightbulb as this option wasn't available on US models, but what about the fluid level light? Is this an issue with the JDM gauge cluster, or is my existing wiring/sensor the problem? Any help would be greatly appreciated, thanks.
