speed sensor wire location
 

Hi , im fitting a pioneer AVIC F900bt head unit to my 1994 BA Astina {1.8L 5 SPD lmanual} it has a wire that has to be connected to the "car speed signal input" circuit , or in other words i need the locatiom of the "speed sensor wire" please could anyone please tell me where i could find this wire ? Thanks for your help.

Are you sure it means speedo sensor? My BL had a speed signal output for the headunit which has nothing to dowith the instrument cluster.
If it is then remove the instrument cluster and the speedo will have three screws -V +V and sig or signal connecting it to the rear PCB.

thanks for your reply.this is quoting directly from the pioneer AVIC F900BT head unit installation manual " connect Pink wire (CAR SPEED SIGNAL INPUT) to the mobile navigation system. It is connected here to detect exact distance vehicle travels. Failure to connect this will result in increased errors This circuit varies from different manufactures check your vehicle workshop manual"
