When I put my swap in, I got some info off of Hybrid Garage that says to wire my knock sensor to D3. I have been having major problems with the car going into loop mode especially when hitting VTEC. I have noticed several places on hondaswap that have said to plug the knock sensor upto B19, but on the P28/P30 Pinout on this site, there is no B19. http://www.hondaswap.com/articles/viewer.php?id=17 Please help!!!
