895XJ Posted April 29, 2017 Share Posted April 29, 2017 I've got an 89 ECU, came out of a 4.0 auto. The ECU offers the 89-90 programming which is the hottest years and yields most power. Free shipping to all 50 states. Very nice condition and corrosion free pins Sent from my XT1635-02 using Tapatalk Link to comment Share on other sites More sharing options...
