Default Speedo reading

Hi anyone.
I have a 1600 Mx5 Mk1 engine fitted and the speedo is in Km/h, I bought a new cluster from a Mk2 that has the electronic speedo instead of a speedo cable, does anyone know if.
A) The speedo sensor in the gearbox of a mk1 (cable) type can be changed to the electronic type?.
B) Can the face of the speedo in Km/h just be changed for one in Mph, or what needs to be done to speedo?.
Cheers Mick.

So it looks like you can buy adapters which convert from a speedo cable drive to an electrical output. You will just need to find the right one which matches the mx5 drive size.

The Speedo face can definitely be changed for a mph one of you can find one. Another option is to put some extra markings on your Speedo face like some production cars have.

Hi Tatey Thanks.
Do you mean the electronic sensor from a mk2 with the correct amount of teeth will fit the mk1 gearbox that has a speedo cable?.
And are you saying that the workings of a Eunos Km/h speedo is the same as a Uk Mph one?.
Regards Mick.

Hi anyone know what colour wire goes to what?
I have got a mk2 nb instrument cluster and the 22 tooth red gear sensor to use in place of the mk1 an cluster.
The sensor has 2 wires a blue/yellow and a blue/white one, the wiring diagram for the mk2 cluster shows orange and a yellow wire, the connectors that came with the cluster doesn't have the yellow wire that could go to the sensor, the only yellow wire joins a black/blue wire grounds for gauges oil,water temp, fuel.
I think L&M of the black connector are are the sensor one L is white/black and M is orange.
Not sure if that's correct and what way the sensor wires go, anyone have any ideas please.
Regards Mick.
