You will need an OBD2A to OBD1 ECU jumper harness along with the stock 96 DX engine harness. Since all the electronics are OBD1 on the motor (if it comes with those parts) you will need to swap the distributor and alternator plugs, you can reuse the stock Y7 injectors on the LS. They flow the same and will keep you from having to change the injector clips. If it doesn't come with the alternator and distributor then I would buy OBD2 parts for direct plug and play. You'll have to do the IACV 3 wire to 2 wire switch at the ECU, aside from that you should be in good shape.

If the motor you are getting comes with the OBD1 alternator and distributor then you can use them but as I said you will have to change the plugs since they changed between OBD's. If not, get the OBD2 parts for complete plug and play.

If you install and wire everything properly you should not have any CEL's.
