i have the same setup as you do... but i got my cluster of a JDM ITR 96 spec. i swaped out the back from my 98 OEM to utilize the ABS sensor. it pretty much works like a 98+ spec now. anyways, i don't think that the 02 sensor would have anything to do with the speedo. in my case one time was that i didn't connect it all the way and it juss slipped out... try the obvious and see if any of the components in the back of the cluster are burned out in anyway, or if anything accidentally disconnected itself. you could also check the wires to see if there is any cut or damaged ones. other than that, i wouldn't kno what else to say.... except that maybe your speedo broke....hope u fix it soon

 

Did you guys switched the green circuit film at the back or did you switch the actual gauges? I did mine and noticed that the ABS, seatbelt and door open dash lights are all switched around like the JDM ones.

BTW, what are the difference between earlier and later models of the JDM ITR gauge clusters?
