Thread: 98 ser harness rear o2 ?

ok so i have a engine harness out of a 98 200sx with a 96 ser ecu on my 98 200sx with a ve, I wasnt able to locate the rear o2 sensor on the harness so i came across a thread or a paper telling me how to add one by moving a pin and splicing into the harness for power etc but still getting no volts to rear o2 so still throwing a code for the rear o2. anybody else come across this problem? chime in, tips, suggestions thanks
