I'm swapping over to a vacuum brake booster in my gs300. I wanted to know, if I pull the ABS computer, will I lose my speedometer? I can't figure out if vehicle speed is determined by a sensor in the trans or at the ABS wheel sensors.
Thanks for the help.

Before anybody says I'm fine with a trans sensor, I'm in the middle of swapping a 350Z 6 Speed that doesn't have a speed sensor.
