I have a 96 gsr motor that is going into a 96 dx using the stock dx harness and an obd1 ecu. Are there any good links out there that show not only the wire conversion at the plug but also what has to be done to the ecu plug?

 

as for the engine harness you should be able to clip the plug and wire in a 2-pin plug. one pin to a12 on the ecu and one pin to 12v source

 

Followed the above diagram when i did my swap, and it's perfect.

 

^^Like what he say. Its pretty simple. Don't forget to get the OBD2A to OBD1 Conversion harness since you are using a OBD1 ECU. P72 or P28 ECU? I think the P28 ECU minus the IAB and need a second knock sensor. P72 you need to add IAB.
