If the replacement engine has the harness and ECM you will just need to plug into the 70 Pin connector in the ECM. There are actually adapter harnesses to do a swap from a 70 Pin ECM engine to an older 40 Pin. However, depending on what cab and chassis/transmission you have there might either be some programming and parameter changes needed or some possible incompatibility issues .
