I'm designing a water meth injection system for Mt Gen 3 and would like some input on where I can tap into one of the speed sensors. The guy that's helping me used to be a Toyota mechanic and he looked on All Data and saw that there is a speed sensor on the radio. Im using a Lingenfelter speed-activated switch to control my water pump. Is that where we need to tap into, or should it be hooked up somewhere else?
