Unhappy Need help on wiring 1990 f150 5.0 - ignition switch

Does anyone know what the purple and white wire that comes out of the ignition switch with all the rest of them go to? Having charging problems and trying to trace it back to ignition switch actuator. Got everything else but, I can't seem to figure out what that one wire goes to. HELP...Please!

Thanks.

The purple and white wire (977) that comes out of the ignition switch pin #P1 then goes to the splice S210. From the S210 it goes to the master cylinder low brake fluid switch and and also from S210 it leaves as a tan light green wire (512) and goes to the RABS module pin #2.
