Component Locations





Located under the far right corner of dashboard, the Service Check Connector is a blue, two pin connector. By shorting its two pins together, the spark timing can be set.

NOTE: In the same location is found the three pin Data Link Connector (DLC). Do not short the DLC pins together, damage to the vehicle may result.
