I was told i have to wire a 4 wire o2 sensor on my da which currently has a 1 wire o2 sensor in order to convert to obd-1. that's one of the things anyway. if i have only one wire??????? where does the other 3 wires attach to? any info is greatly appreciated as this is one of few issues keeping my teg from it's full potential. lol

 

i forgot to say it has a b-16a. i don't know if they only have 1 wire o2's or if that's a da wiring?
