Ok so I have a 97 dx ek hatch and I did the y8 head on the y7 block, I understand the whole 3 wire iac conversion too 2 wire iac. I understand the wiring in the vtec, here is my issue I think my buddy wired in the vtec wrong to the plug that goes into ecu that and every plug I find online says that the Grey plug is the A plug and blue is B. Why does mine say a on the blue and b on the grey? Does anybody have pics of how they wired there vtec into main harness?
