Anyone know what kind of signal the SD1 speedo take off gives out, trying to establish if it would be possible to use this with the smiths Telemetrix range.

Cheers

Could be wrong but isnt the lt77 sd1 a cable drive speedo...

as I said I could be totaly wrong...

the box I have has a geared transmitterx which bolts onto the back of the box (near output shaft) with two leads from it, this is not the reverse switch

Cheers

Here is the wiring given to me on the V8 forum hope this helps

The Vitesse speed sensor has three connections.

* The body is earthed via the gear box - no colour of course.
* 12 volts in, on a white wire from the ignition circuit.
* Speed signal out, on a red/black wire, which may then change to black/red if you have the extended harness and thus goes to the Vitesse speedo, trip computer and cruise circuits.

cheers for that
