ABS light self test location help me please.

[houster2001]

I know there is a way to get the codes and clear them by grounding a lead under the dash for the ABS light. It will flash and and flash again and you can ground it three times to clear the codes. I can not find the lead to do it with the FMS shows lead (L) on the check connector I can not find it there is one connector in that area that has like 8 wires and one off to the side by itself in the same plug but that wire I grounded and nothing happened can anyone help me please
