The convertible top motor in a 1969 Oldsmobile Delta 88 is located
in the trunk, typically on the driver's side (left side in the US). It's often mounted to the inner trunk well, near where the convertible top mechanism itself is housed. You'll likely need to remove some interior trunk panels to access it.
However, the exact location might vary slightly depending on specific model variations. Consulting a 1969 Oldsmobile Delta 88 shop manual or a parts diagram would be the best way to confirm its precise location.
