Jeff,
You are right, it is hard to see which one is the positive or the negative
on the pump.  But its there.  The x will be the positive.  The wires are
different too.  One has two colors and one of the colors is red, and that is
positive.  The other is black or brown wire only.  That is negative.  I
think, it makes the motor run different direction if you change them.

Subject: fuel pump wiring 87 2.1 van a/t

I just replaced the fuel pum in my van.  How do you tell which wire is
supposed to attac where?  On the new pump there is an X near one of the
terminals and no marking on the old.  They are both Bosch pumps.

Thanks,

Jeff
