If you don't have the A/C ambient temperature sensor, the same type of sensor is also used to measure the air intake temperature. That sensor is mounted on the intake tube located above and behind the left turn signal.   2. The wire that goes to the vehicle speed sensor is not primarily for the compass. It doesn't care about vehicle speed
