I was told that you cant use a Stealth tracker from a R1250GS or R1250RS SE on the new R1300 GS due to the loom being different. However this is not strictly correct as Datatool came and “hard wired”my one in directly rather than use a loom. They charged me around £95 to do this so a cheaper option rather than replacing the tracker. My insurance company insisted on a Tracker rather than the alternative. Hopefully this may enable your sale.
Bump for your sale.
