I have a b18c and a chipped p72 ecu is the stock wiring harness for the motor going to work or not. I need to know before i buy it. I have read and read but still dont understand why I need any modification if i'm going from a gsr engine to a gsr ecu. At the cost of looking like an idiot please clear this up for me. Thank you in advance
 
call rywire and tell them what you have and are doing and they will sell you a plug and play kit
