I bought the car 3/4 complete but CBM supplied all of this including fan relays, software and the pigtail for the laptop. I would get as much from them as possible because I know the guy that built the car tried to be involved with doing as much on his own as he could. He missed a few thing like getting that valve thing on the s/c working and the mefi requires a different GM knock sensor. Those problems cost me dyno time. The computer, fan relays, fuse box, ect is all mounted in a Pelican case. Even the laptop pigtail is in there. Nice and neat and well protected from the elements.
