The printed circuit board in my 93 LX wagon (auto) had problems when I bought it a few years ago such that the speedometer and odometers didn't work because of corrosion on the printed circuit board. I installed a board from a 93 LX sedan, everything now worked, but the speedometer was off. I then installed the 130 mph speedometer from the sedan and it worked correctly.
Now that replaced board has another area of corrosion that causes all the door / hatch open lights to come on dimly all the time. I cleaned the corrosion as best I could which appears to have restored the door open function (all black unless a door is open), but now the temperature gage goes straight to HOT when you turn on the key. I'm kicking myself because I checked the function of the door open lights, but not the other functions before I put the dash bezel back, radio, and console back in.
I have an extra 93 LX sedan cluster, but its board is corroded even worse at the same location.
I was only able to find a cluster from a 93 EX sedan today at the JY with light corrosion in the same area as the two clusters above (what is it with this location?).
Any one know if the EX board will work in the LX cluster (I know it wouldn't work the other way around)? The only difference I see is the "ABS" light on the EX cluster. There is a blank space at that location in the LX cluster. Will all the other circuits work?
Any one have a clean LX sedan automatic cluster circuit board? Majestics's site indicates the board is no longer available (almost $1000 list price if it was!). With all the corroded ones I have, I may see if I can solder wires between the appropriate pins to replace the corroded circuits on the board.

Looks like I answered my own question. Installed the EX circuit board, door open warnings actually check correctly (on for two seconds) when turning the key on, temperature gage stayed cold. It's very late, so I didn't go out and drive it.
I noticed with both clusters apart that the "ABS" light is in a separate smaller circuit board at the top of the cluster assembly underneath the large circuit board. The LX cluster appeared to have the same smaller board, just with an empty light socket where the "ABS" light would be. Everything on the main circuit boards looked similar.
