Hey guys im going to be wiring up my megasquirt soon and it accepts a VSS sensor input. I was wondering which one i should use. I know that their is a sensor that is in the combo meter that is run from the speedometer cable or i could use the ABS sensor in the rear of the r154. Which would be best to use or does it matter? Thanks
