Here's a pic of the orientation of the valve when mounted correctly. There are 2 holes for the bracket, you want the wire leads coming off the valve going toward the center of the intercooler, not toward the outside. I found this out the hard way and had to remove it. Wires hit the frame when put back together unless mounted as mentioned. They provide 2 brackets, the directions show both being used at the same time, and that just doesn't work. I used the simple L bracket and it lined up with the mounting hole and secured the valve.
I could not get the intercooler out of the truck. The fans made it difficult (not present on normal f150 according to Stage3 install video), but I could not get the OEM bov past the driver side pipe/elbow off intercooler. I ended up removing that hard plastic 45° elbow completely and just sagged the left side of intercooler down to install the new valve. Be careful of the wires that need detached above the valve. I also loosened the charge pipe connections on passenger side to help with this.
