1998 ranger 2.5 5 speed 2wd Have ABS light on and have not been able to clear it. Changed the VSS and plug is good. Now at shop and the mech. cannot connect to ABS system, [no power] where is this system powered from?? The large fuse box under the hood shows a 50 amp fuse in the third slot, but the slot is empty, and there are no contact points for a fuse, like it was never there. Is there another source of power to the system,and if so where is it?? Any help appreciated.
