You will have to eliminate every possible short on the vehicle before installing the ECM or the computer will be damaged again. Replace your idle control valve (IACV-AAC) and throttle position sensor. Closely check the wiring harness and connector to the IACV valve. If your computer gets burned again as a result of failing to follow this warning, warranty will be voided. 

Your vehicle keys must be reprogramed for the new computer. Reprogramming procedure can be performed by a locksmith that works with car keys, at a repair shop that has an appropriate scanner, or at your local Nissan dealership.
