I also removed the OBC completely and removed the solenoid bracket and fin in the top corner and welded a plate over the OBC hole to give me the most room. I have a SW200 solenoid and it is huge. Take time routing the wires, go to the alltrax website and they give some great pictures of the install, for wire routing. I also added a USB extension and I have the FNKS box for the XCT. Mine still fits behind the back cover. I made a couple of extra holes for air movement. I know how muddy it gets I didn't want all the mud in that wiring. These are pictures of my install.
