I have a 1990 S13 with a KA24DE. My IACV is broken but uses the old square connectors. The harness side is an 8 prong connector, but has 2 of the prongs missing (looks like it came that way). The new IACV design has round connectors has 8 prongs (none missing) on the harness side. Does anyone know if I can swap the sub-harness and use the newer IACV design? Or are those 2 extra prongs going to be a problem?
