Hello, I am trying to figure out everything that I need to install a K20A motor in a 2002 Honda Civic Ex (ES2 Chassis (I think)). I am planning on purchasing the motor from H-motors and I noticed they do not include the fuse box. So I was wondering if I should purchase a fuse box for the K20A motor? The reason I am thinking this is because with the motor you get the exterior wire harness and you use a kit for the interior wire harness. Since I am using the exterior wire harness, shouldn't I need the fuse box to make the install easier?
