From 1992 sometime soarers got an outside temp display in the dash. many people have asked how to get this.
Simple.
You need the correct dash.
You also need the correct A/C computer.
That's it.
No wiring changes. Just plug them in.
And NO, neither the early dash nor the early A/C computer can be modded to work. You need the correct ones.

Is there any way to know if its the dash thats wrong or the A/C computer? My dash has the "C" on the display and says "OUTSIDE TEMPERATURE" at start up but no temp reading.

Then it is the Aircon computer that is wrong unless the dash has been butchered internally and then it'll be both.
Could be just the sensor and/or wiring but then the A/C would generate error codes.

Usually it is because the dash has been changed.
Sometimes a faulty sensor.
I've never heard of an A/C computer being faulty especially the EMV one.
The non-EMV ones get changed regularly because the display on the front of them bleeds but the EMV A/C computer is up under the dash and most people only ever notice it when doing a manual conversion 'cos they have to move it.

It is the dash's in these cars that give trouble and so it is them that are most often swapped hence they are the most likely culprit. It is only recently the Japanese even attempted to repair one and that was because of the tutorials getting around the place. The usual Japanese mentality is to grab one from the latest model wreck if possible or a new one if not. Either way it'll have a lower odo. And it'll be the later model probably so will have the temp display.

That is why there are so many cars around with "low mileage" and not any deliberate attempt at winding odos back. that is expensive and not easy.
Even dash's changed under warranty by the dealers weren't wound on to the correct reading if the customer asked but noted in the service history instead. I suspect that this is one reason why the service history of a car gets "lost" but all the other stuff is there in the glovebox.

Thanks for the feedback Mark, My car doesnt have the EMV, but it does have the temp sensor on the front bumper, so Im thinking that its the A/C computer.

Wouldn't you also need the little probe that bolts onto your bumper ?

It should already have one anyway as it's used by the A/C.

As far as I know it should be possible to get the temp display in ANY car by changing dash and A/C computer. Everything else is there and there are NO wiring changes. The temp display is probably done via serial link that is already there, just modified data to include the temp display.

ALL of the above is specifically related to non-EMV cars but EMV equipped cars are probably the same, just a different A/C computer setup.

Resurrecting this one from the grave..

Would like to get a readout on my temp dash in my 91 soarer

I had a 94 model v8 with the degrees C on the dash, but no reading, and a AC unit which was just on 100% fan all the time.

I swapped out the AC unit with a different one trying to fix the 100% fan and it cured that as well as providing the temp on the dash.

Do you know what the part number of the replacement unit was that fixed the problem?

The part number on my original 94 unit is 55900- 24160 then 146430-4067. I think the earlier units had slightly different pin outs the post 94 units.

you can just swap them out but you need an a/c module from 92.5 onwards and a cluster from 92.5 onwards but before 94 otherwise you'll have other issues.

Don't suppose anyone knows the part number for the 92.5/93 AC unit?

Can anyone with an early model AC unit and temp dash please tell me the part number on the back part of the AC unit?

This is an old thread, but here is hoping that some knowledgeable person sees this, so here goes. My '92 SC 400 odometer was almost completely bled out and I decided to change the cluster. The only unit that I could find does not have an external temp readout. I also understand that this is either there or it is not, so no jumper option. I like having the external temperature. Is there any (realistic) way that I can change the ODO by itself? Are they even available? BTW, I am in Victoria. Thanks, Colin

Off topic, but.... I just killed a headlight globe. Everyone tells me HB3 or HB4. I know the tabs are completely different to the globe that came out (2 skinny, 1 fat tab). Why is it that one has to modify something that comes new in a box, just so that it can fit???

Just pulled the old cluster apart and it looks like it should be an easy swap for the ODO chip
