I am adding a link to the Xantrex Battery Temp Sensor cable........http://www.xantrex.com/documents/Battery-Chargers/XC-Battery-Charger/XC_BC_BTS_lnstall_English(975-0193-01-01_Rev-A).pdf
I am adding a manual for the SW4024 unit you have if you don't have one. The RJ-11 plug is the same on both the old style cable and the new one and so I do believe they will work........but, I would ask Xantrex just to be sure. If you need that contact info please let me know. Hope that proves helpful here.
