Installed new rear hubs today. Took screenshots from VIDA, since one cannot screenshot or export as PDF from VIDA, at least on mine install. Haldex overview & CAN signal I/O description Not sure there is any point cutting a hole for the PS (main) sender, as that cannot be removed unless you also lift the DS sender to release the cross tube and level sender wiring. Looking at the floor, the PS unit would have to be cut right where the seat belt mount is located. It's also not a flat area. I dunno. Not sure I want to mess with this now.
