Fitting a greddy turbo timer - What colour is speed wire?
 

As above. I'm going to be fitting a GReddy Turbo timer, with the RX7 wiring loom. As i've got the loom, i've not got to fanny about with the ignition leads, but I have to connect the handbrake wire and a wire to the speed sensor (if available). Is there a wire going to the ECU that I can connect the speed sensor to, and if so what colour is it?

Thanks

Forgot to say, its a 93 FD
