Haha, i love how everyone is bragging about how fast they can get to their ECU box. Yes, it's very simple after you've done it a couple of times, but it could take a first timer an hour or so.
Just take your time and be patient man, it's not a race! Here's the video I used to install my PROcede, it's very clear and if you follow the instructions carefully, you shouldn't have any issues.
