Speed limit : 180km/h ?

yep. You will also notice a 112 km/t limiter on the cruise control. You also need a SLD for that. So one placed by the ECU and one by the cruise ecu. I'm having trouble with the last one, as I think the cruise ecu is placed so it is almost impossible to get to :-(

It does the job. There is - as far as I know - not really any difference in any of them, as it is just a conversion of the voltage that is forwarded through the speed connector to the ECU. Very simple. You will need to cut the pink wire in the top, right hand (as far as I remember) corner of the ECU connector and wire in this SLD. It also needs 12V and ground. But be really sure what you are doing before cutting any wires to the ECU.

Sorry, it's not all facelift auto's that's difficult. I'm only certain that it's the 98 vvti that is. Not sure of the 96-98..

 

Regarding a speedo, you should go for a replacement. You probably can keep the 180kph but I don't know what happens when it goes for the second round. Maybe you can do a kph/mph conversion?

You can get a 180mph/320kph for maybe 150£ or go for the more sought after TRD version. Don't know if that is available on MPH though. But it is a straight swap. No real problems there. The odo might be an issue if you want to convert to miles. Do a search for that. I'm in Denmark and we do kph :-)
