Only the same size that you are taking out will fit without modifications.

The wiring harness will not work. In 1992, Dodge introduced the "Magnum" series motors. These motors were MPFI (Multi-Point Fuel Injection) motors whereas the motor in the 1990 Dakota was TBI (Throttle Body Injection.) On this fact alone, you'll be missing the connections required for the fuel system if you use the wiring harness. The computer management systems were also vastly different so you would not be able to plug into the Engine Control Unit (ECU) with the wiring harness.
Yes

if it is the same size and year then yes but you will need oil pan off dakota.
A 1989 Dakota has throttle body fuel injection.
