I did a little bit of searching, but couldn't find any threads on the installation of a Apex steering boost kit on a 392. The Apex site has a install video but doesn't address the 392. Tried to call and email with no feedback. The typical JL has the air box over the electric steering pump, so it can be pulled from the top after removal of the air box. The 392 has the computer and fuse box over the steering pump which is slightly visible from the top. I'm reluctant pulling the fuse box and computer. Has anyone personally done an install? How did you do it and where did you place the cooler?
