I finally broke down and purchased the X-5 Smartpilot Wheel. It came yesterday and I have been reading the installation and operating guides in preparation for installing it this weekend. The one meter distance requirement from metal objects (engine mainly) and other electrical/magnetic interference items begs this question in my mind... where the heck are the corepack and fluxgate typically installed (successfully) on H33.5's like my 1988 model? Any help appreciated!!
