What are these wires ?

That was first thought and first checked. One lead on regulator and it's occupied. THX

There are two wires that attatch to the regulator. Most likely the ones shown. One is a "plug" type and the other is "spade" which is connected by a slotted screw on the reg. If I see correctly in the pic, the plug wire going into the reg., looks to be for brake warning light. Hope this makes sence.
