I've asked this question in Club Titan and Titan Talk and no one can give me a solid place to tap into the VSS. I will not tap into the wire at the ECM in the engine compartment, it has to be in the cab. All of the white/red wires I tested did not show a voltage spike while moving. Unless I tested them wrong. And that link at the beginning of this forum turned up with nothing for my truck. Can somebody please help :?:
