Tested in running and driving condition, pulled from a non-wrecked 1995 Jeep Wrangler YJ, See below for exact fitment details **Attention** If you have security on your vehicle you will have to take this to a dealer and have them flash it to your vehicle. We always recommend installing computer first and trying it, often times they are plug and play but there are occasions where Mopar requires a flash to be done when replacing your vehicles computer. Fitment:1994-1995 Jeep Wrangler YJ with 2.5 Liter Engine and Manual Transmission Other Possible Part Numbers:56028828 Warranty:Since we pull our computers off non-wrecked vehicles, and every single one gets tested before pulled and shipped, all sales are final. If you plug in the computer and get the exact same issue, your issue is not the computer, if your vehicle runs and days later flat lines again, you have something else causing your vehicle to eat the computer. These are not common experiences, typically customer plug in our computer and they are good to go. If your vehicle has security it will need to be re-flashed to your Vin and Key to work.
