U R probly right about the wiring. If you don't have one already, a VOM to check the wiring would come in quite handy for you right about now. You would do much better to look in your FSM under PFI system diagnosis and understand the circuit, follow the procedures there to help pinpoint the source of the "open TPS circuit" than relying on the Haynes. It is nowhere near as helpful for this kind of thing.
