Yes it will as long as the ECU is from the same drive train (E.g. 4x4, 4x2 automatic, manual.)

The bulbs should be checked on a 1993 Dodge Dakota if the taillights are not working. The plugs on the trailer package should also be checked to make sure that they are working.

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.
In my 1989 Dodge Dakota the brake light is on fuse number13 it is a 5amp it also goes to buzzer, speed control, check engine light, anti-lock warning light, and other things page 12-19 Haynes 1987- 1993 Dodge Dakota Repair Manual
