5187157 2007 Jeep Wrangler 3.8L Plug & Play ECM PCM | 05094149AF

Easy plug and play, I had to take the old ecu out and it worked after installing. No misfire on my cylinders and the vehicle is now running beautifully. I just sent over my vin # and the company matched my vehicle to the correct ecu. I took it to a local Firestone for a diagnostic and they recommended that I take it to the dealership to get a new ecu and they would have to program the part to the vehicle. I chose to shop around and found an ecu already programmed. Best choice, saved money and time and did it myself, thank you ARES Technologies!!! Very easy to install and if you have issues, you can watch a YouTube video on installing an ecu on a Jeep Wrangler.
