i wedged myself under there last night to pull out my ecu, and it took me at most, 15 minutes. the hardest part is getting comfortable down there...and trying to figure out how the hell you're going to use your arms in that cramped space. the best thing to do it pop out the black plug that holds the wires close to the mounting bracket...remove the brown thing and silver thing from their brackets (and push them out of the way)...and then go at it after you pull the electrical connectors. make you you have some kind of work light down there with ya...maybe a fan for some air too. oh...make sure you use a tool small enough to squeeze up by the top two nuts...my ratchest with adaptor was too big, so i had to break out the wrenches. it was a tight squeeze for me, and i'm a little guy (don't even go there you sickos)
