pioneer vehicle dynamics

i got the pioneer dynamics thing but i have a question does any body know what wire from the cars computer ( i have a 95 240sx s14) gives out the speed detection pulse i need to know cause im not paying 65$ for them to conect 1 fucking wire for me + when it said connect the violet/white wire to the wire that when the car is in reverse the voltage changes so does this mean i connect this wire to the back up tail lights or what?
