How can I convert my d16y7 harness to work for my jdm 99 B18C Type-R motor? What all needs to be done. And why do the USDM harnesses use a vtec switch wire and the JDM harnesses don't? Will I not need to run the vtec wire? I'm sorry if this has been covered before, but I couldn't find it. And does anyone have the rear motor bracket and side mount for a 99-00 civic si they would like to sell?
