Well Im not familiar with s14sr's par say, but I can tell you that as long as the power plug is the same between the models(should be?) the motor will run if the harness is plugged to the same ecu it was spliced for, no matter wat car you put it in. The only thing to worry about are the cluster, ac, if you have cruise and any features in the car.

But yes, just make sure the main power and ground are right (plug by battery, or should be. Never done an s14) for your harness and you can plug the motor in and run it.

If stuff doesnt work such as your tach, speedo, or ac, you can just find the pin out and run that wire from the ecu plug side directly to you speedo or tach wire, or ac. And as far as ac, you can pretty much just put that on a switch if you need to. But yes, the engine will run, your cluster may or may not work properly. Can someone else chime in?
