90 rad. fan question

[Derick Farfan <bg18461@binghamton.edu>]

on my 88 90(fwd)) the connector that goes to the radiator motor has
official fully corroded.  i made a replacement, but i made a foolish
mistake.  i did not mark which of the three wires go to which three
prongs on the fan.  the colors are red/black, red/gray, brown.
for lack of a better drawing this is how the fan looks looking at it
while its in the car
