'89 240sx Oxygen Sensor Wiring Issue

[kurtwolff]

I just got an '89 240sx Coupe. KA24e motor, still I noticed it got horrible mileage on the drive home (approx. 130 miles, used over 1/2 tank). Checked it out, the o2 sensor wire was cut. Also spliced in 4 places. I looked on the .pdf of the service manual, and can't seem to locate where the wire should go. Have any of you had to re-run the wiring for the sensor? Where should I splice back into?

Thanks so much, I NEED to get this back for some decent mileage!

ITs called exhaust gas sensor in manual. You might need new one as they go regularly.

factory service manual in my signature. for the ka24de(91-94) there is a white wire going to terminal 19 on eccs control. theres a black wire that goes to throttle position sensor and engine temp sensor. black wire eventually goes to terminal 29 on eccs control. the wire going from sensor to plug is one wire but there are actually two wire . I made the mistake of cutting that and it took major surgery to separate the two wires and splice them.
