@Skyye As long as it's in as good a shape as it appears, it should be plug and play. This car so old this ECU just barely qualifies as a "computer". It prob can't even run Doom. And if the car runs but still a little oddly, at least now I'll have a spare in it so it will get partner to work while I send the def bad one off to be remanufactured. I was gonna buy one off RockAuto for 300 but I realized the part number was wrong so I went eBay. Better than aftermarket, those are 1500 lol.
