4 wire o2 sensor

  1. 4 wire O2 sensor

    Engine - General, Exhaust & Induction
    Can someone direct me to a site/picture or tell me how to make a 4 wire O2 sensor work on my car? (Unless '88 used them anyway) I have an '88 harness and computer (from a SL) that plugs into an '87 bulkhead connector. I also have a TD model of the Dawes Device that I need to wire in as well...
