Those are the connection for the oxygen sensor in the cat converter. The single is the connector and the 2 wire set is the heating wires for the ox sensor. they connect into the brain harness.
Also, there is a 3 wire plug that is sometimes used to run the sensor with a connector that is offset in the connector so it only fits one way. Get the other ox sensor so you match the brain harness.
The split appears to be between 85 and 86.
