Where is the 4 wheel drive actuator on a 1996 Chevrolet S10 pickup located?

The 4WD actuator on a 1996 Chevrolet S10 Blazer/Jimmy (the S10 pickup truck used the same system) isn't a single, easily identifiable unit like a motor. Instead, it's integrated into the transfer case. There isn't a separate actuator housing; the mechanism is *inside* the transfer case itself.

To find it, you'll need to locate the transfer case, which is positioned in the middle of the vehicle, near the transmission. You'll then have to remove the transfer case to access and inspect the internal actuator components (shift motor and related linkage). This is a significant job requiring mechanical expertise and specialized tools.
