GPS speed sensor

[Uri]

I´m replacing the Oem radio for a double Din Kenwood with GPS but I don´t know where to plug the white cable coming from my GPS. It´s the speed sensor. Does anybody know where does it goes? Thanks

Done it!
Here is a list with lots of speedsignal.

Another site showing how to find the NSX Tachometer signal wire. May be interesting.
