Does anyone else have an extra wire in their wire bundle after the connector for B2S1 sensor? I just replaced my sensor and noticed my wire after the connector got a little melted from touching the manifold. When I cut back the tape on in, I noticed an extra bare wire not connected to anything, just wrapped together with tape on the black wire. Does anyone else have this? Just trying to figure out what this extra wire does or if it needs to be connected to something.
