frankMart Posted June 23, 2013 Share Posted June 23, 2013 I have a 87 2.5, today I found a 89 2.5. I grabbed the ECU. The question is: Are there any difference between the 87 ECU and the 89 ECU? Is it just plug and play? Or will I have any trouble? Link to comment Share on other sites More sharing options...
Eagle Posted June 23, 2013 Share Posted June 23, 2013 They are both Renix throttle body systems, so even if there are some differences, overall the swap should work. Link to comment Share on other sites More sharing options...
Geonovast Posted June 23, 2013 Share Posted June 23, 2013 Was the 89 an auto or manual? Link to comment Share on other sites More sharing options...
frankMart Posted June 23, 2013 Author Share Posted June 23, 2013 It was manual. Mine is a '87 2.5 5 speed, the other was a '89 2.5 5 speed. Link to comment Share on other sites More sharing options...
Geonovast Posted June 23, 2013 Share Posted June 23, 2013 Yup, direct swap then. Link to comment Share on other sites More sharing options...
VixJeep Posted June 26, 2013 Share Posted June 26, 2013 I bought a remanufactured ECU for my 88 4.0 for $125 online. Works great and the price was reasonable. Link to comment Share on other sites More sharing options...
