Default Swapping guage clusters? 93-94

Does anyone know the specifics involved? I'm curious how that works with the digital odometer. As you may have noticed from my eventually removed thread I was looking for another cluster to get some parts from. I ended up pulling one out of a wreck and it has a rebuild sticker on it from BBA. I paid $25 which is the cluster deal of the century. But, I'm wondering if I can just toss the whole thing in my car rather than totally disassemble it to get the temp gauge and tach needle out. I could plug it in and see what happens but I don't want to set off some type of tamper prevention security.

Your new odometer will show the mileage from the car it came out of, but no alarms or anything will go off, everything will still work as normal.

The odometer can be reprogrammed. There are DIY tutorials available for this on Toyota cars. It will involve taking apart the cluster. More details here:

Thank you, this answers my question. Now I know the odometer assembly contains it's own information about mileage and doesn't reference another source. Good to know. I took apart the newly acquired cluster and removed the tach needle assembly and the temperature gauge, then I put my original cluster back together with these parts. It's actually a really easy job to do. Swapping the odometers so I could keep my mileage with the other cluster would have been a equally easy task. Anyone with common sense and some small screw drivers could do this work.

For some reason the links are not working. I would like to read it to understand the system better. Ah, found it on google. Yea, plain old EPROM chip setup.

Sorry for the inconvenience. Never had that happen before with the links. They should work now, but yes, they are just EPROM chips.
