Complete computer, actuator & sensor wiring diagram for 88-90 Mass Air Mustangs


Use a Multimeter or DVM to check the continuity between the wire on the sensor and the pin on the computer. Adding a few feet of extra wire won't make more than 1Ω to 2Ω difference, not enough to invalidate your results. When you have continuity between the sensor wire and the computer, a good quality meter will usually beep. If you have the el cheapo version, you watch the meter scale for a reading less that 5Ω.
