So after much research and testing the VSS in my 2008 mazdaspeed3 is one of the most f'd up wires I've had to deal with in a while. I found a signal at an empty pin at the gauge cluster BUT it only sends a signal when the brake pedal is depressed. Anyone have any access to the cluster diagram or knows a way that might reverse the signal would be a godsend. I could do it with two relays but i would like to hear some other options.

yea but i don't think the turbo timer accepts a negative pulse because i had no signal when it was hooked up.
