I have a 1987 E-250 with a 302, auto trans and power steering. I bought it
used 15 years ago with 58,000 miles on it. It's at about 120,000 now. I
don't remember that the steering was all that bad back then but some time
later it was, and I replaced the steering box, tie rod ends ...

Can anyone tell me the wiring connection for this item.  It has 3
wires, 1 black and 2 white.  One is 12v+, one is 12v-(the black one I
assume) and one is the output voltage.  There is no indication on the
part or the package which white is which.  The wires exit the part on
