So if you in the US chage the gearbox then you use the speedsensor on the front diff. And then i belive the speed cluster has to be change to, for then i lose the KM/H and must have MP/H are this also rigth? I have US speed cluster at my home also, But i have try this on the car and my car will not read this corekt.

(Pleas corekt me if i am wrong)

Alex I suggest you get an auto electrician to read carefully the last paragraph in Phil's post above, #68, and follow these instructions carefully. I am presuming also that you still have a Hall Effect sensor for SS2 installed in the front diff housing. If this is not the case please tell us.

The speed cluster from your own car should work. It gets its signal forwarded from the TCU, and I think [but don't know for certain!] that your original box probably had the same Hall Effect sensor on the diff. Can you remember?

The sensor merely measures the number of times the axles turn, and this information is sent to the speedo as a signal. It should make no difference to the speedo hand whether it is passing a kilometres figure or a miles figure on its way round the dial; the speed is displayed by how far around the dial the hand is sent.
