I have a 2000 civic ex with a 96-98 B18c5 swap. Currently i am running a p2t ecu out of a 99-00 civic si. I do have the p73 ecu and I am wondering what all is needed the install the ecu. Is all I need is a jumper harness from obd2b to obd2a? I have read a few forums stating that the vtec control wire needs to be hooked up. Is this also true?
