Q:

A: What year is your 306???? I have the instrument panel from a 306 in front of me now. It is from an older model (1994) with 13 fuses, not the newer models with 30 fuses in the fusebox.. The trip reset button is directly under the trip-ometer about 1 inch. It protrudes through the plastic face of the instrument panel. You simply PUSH it in to reset the 4 digit counter. If you do NOT have this, then your 306 must be a newer type with electronic speedometer and tripometer. Sorry... I don't know the answer to that model's trip-ometer.
