im swapping a gsr into my 96 ex coupe. im ready to drop the motor into my car, ive been told to use my stock ex wiring harness, so i need to know what i have to modify on my ex harness to work on the gsr motor. also i need to know what pins i need to change around on the plugs that plug into the ECU. also i am using the ecu that came out of the same car as the engine. any help will be appreciated...thanks
