WARNING: This page is about a different car, the 1988 Cadillac Seville and 1988 Cadillac Eldorado. However, it is still accessible from the selected car via links, so may be relevant.

When main relay coil is NOT energized, the relay provides a ground path for circuit No. 850 through circuit No. 150 at front sheet metal ground.
