HI i was just wondering what exactly is required with the wiring to swap a 99gsr b18c1 into a 00 civic ex. I've heard the a knock sensor is need and a iab is required then again i've heard only the iab. So i know this is one of the most commonly done swaps out there, but i wanna know once and for all. And i was also wondering if anybody know anything about if i would need to have the GSR computer flashed to have it reset before it will work agian i've heard it was some sort of anti theft device on the 99's. And would it be easier to just use my ex wiring harness instead of the gsr's and just add a wire. Thanks for all your help.
