I have a problem. Ha. that may be a understatement. I want to know can I use a 3 wire IACV with a OBD1 conversion. Do I absolutely need to switch to the 2 wire or is there a way to wire the 3 wire IACV in? I have tried a couple things with no luck. P.S We are working on a 98 Civic DX it was auto trans now has a Manual swapped in. Turbo blah blah blah. You get the idea.
