I have a 98 Hatch Dx. Recently swapped to a D16y8 with harness and ecu. I’m aware I have to wire in the secondary o2 sensor. My question/concern is my Y7 has 2 wire connecters on the driver side near the brake booster and the Y8 harness only has one connected there. Do I need to be concerned about the other connector? Does anyone know what it’s for? No connectors on my Y8 harness are unconnected.
